The OP183 is a single-supply, 5 MHz bandwidth amplifier with
slew rates of 10 V/μs. It can operate from voltages as low as 3 V
and up to 36 V. This combination of slew rate and bandwidth
yields excellent single-supply ac performance, making this
amplifier ideally suited for telecom and multimedia audio
applications.

The OP183 also provides good dc performance with guaranteed
1 mV o

ffset. Noise is a respectable 10 nV/√Hz. Supply current is

only 1.2 mA per amplifier.

This amplifier is well suited for single-supply applications that

equire moderate bandwidth even when used in high gain

r
configurations. This makes it useful in filters and instrumenta­tion. The output drive capability and very wide full-power
bandwidth of the OP183 make it a good choice for multimedia
headphone drivers or microphone input amplifiers.

The OP183 is available in a SO-8 surface-mount package. It is
sp

ecified over the extended industrial (−40°C to +85°C)

temperature range.

For supply voltages less than ±7 V, the absolute maximum input voltage is

equal to the supply voltage. Maximum input current should not exceed
2 mA.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Stresses above those listed under Absolute Maximum Ratings

y cause permanent damage to the device. This is a stress

ma
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Absolute maximum ratings apply to packaged parts, unless

herwise noted.

APPLICATIONS

OFFSET ADJUST

Figure 33 shows how the offset voltage of the OP183 can be
adjusted by connecting a potentiometer between Pins 1 and 5,
and connecting the wiper to V
the potentiometer is 10 kΩ. This will give an adjustment range
of approximately ±1 mV. If a larger adjustment span is desired, a
50 kΩ potentiometer will yield a range of ±2.5 mV.

This arrangement drives the transformer differentially so that

he drive to the transformer is effectively doubled over a single

ability of the OP183 to drive capacitive loads and to save power
in single-supply applications.

PHASE REVERSAL

The OP183 is protected against phase reversal as long as both of
the inputs are within the range of the positive supply and the
negative supply −0.6 V. If there is a possibility of either input
going beyond these limits, however, the inputs should be
protected with a series resistor to limit input current to 2 mA.

DIRECT ACCESS ARRANGEMENT

The OP183 can be used in a single supply direct access
arrangement (DAA) as shown in Figure 34. This figure shows a

ortion of a typical DAA capable of operating from a single 5 V

p
supply; with minor modifications it should also work on 3 V
supplies. Amplifiers A2 and A3 are configured so that the
transmit signal TxA is inverted by A2 and not inverted by A3.

LOW VOLTAGE HEADPHONE AMPLIFIERS

Figure 36 shows a stereo headphone output amplifier for the
AD1849 16-bit SoundPort® Stereo Codec device. The
pseudoreference voltage is derived from the common-mode
voltage generated internally by the AD1849, thus providing a
convenient bias for the headphone output amplifiers.

3 V 50 HZ/60 HZ ACTIVE NOTCH FILTER WITH FALSE GROUND

To process ac signals, it may be easier to use a false-ground bias
rather than the negative supply as a reference ground. This
would reject the power line frequency interference which can
often obscure low frequency physiological signals, such as heart
rates, blood pressures, EEGs, and ECGs.

Figure 38 shows a 50 Hz/60 Hz active notch filter for

liminating line noise in patient monitoring equipment. It has

e
several kilohertz bandwidth and is not sensitive to false-ground
perturbations. The simple false-ground circuit shown achieves
good rejection of low frequency interference using standard off­the-shelf components.

Figure 38. 3 V Supply 50 Hz/60 Hz Notch Filter with Pseudo Ground

Amplifier A3 biases A1 and A2 to the middle of their input
common-mode range. When operating on a 3 V supply, the
center of the common-mode range of the OP183 is 0.75 V. This
notch filter effectively squelches 60 Hz pickup at a filter Q of

0.75. To reject 50 Hz interference, change the resistors in the
twin-T section (R1 through R5) from 2.67 kΩ to 3.16 kΩ.

The filter section uses OP183 op amps in a twin-T
co

nfiguration whose frequency selectivity is very sensitive to
the relative matching of the capacitors and resistors in the twin­T section. Mylar is the material of choice for the capacitors, and
the relative matching of the capacitors and resistors determines
the filter’s pass-band symmetry. Using 1% resistors and 5%
capacitors produces satisfactory results.

LOW VOLTAGE FREQUENCY SYNTHESIZER FOR

The low noise and low voltage operation capability of the
OP183 serves well for the loop filter of a frequency synthesizer.

CRYSTAL

REFERENCE

OSCILLATOR

PHASE

DETECTOR

3V

OP183

Figure 39 shows a typical application in a radio transceiver. The
ph

ase noise performance of the synthesizer depends on low
noise contribution from each component in the loop as the
noise is amplified by the frequency division factor of the
prescaler.

The resistors used in the low-pass filter should be of low to

oderate values to reduce noise contribution due to the input

m
bias current as well as the resistors themselves. The filter cutoff
frequency should be chosen to optimize the loop constant.
