GENERAL DESCRIPTION
The OP400 is the first monolithic quad operational amplifier
that features OP77-type performance. Precision performance is
not sacrificed with the OP400 to obtain the space and cost
savings offered by quad amplifiers.
The OP400 features an extremely low input offset voltage of less
tha
n 150 µV with a drift of less than 1.2 µV/°C, guaranteed over
the full military temperature range. Open-loop gain of the
OP400 is more than 5 million into a 10 kΩ load, input bias
current is less than 3 nA, CMR is more than 120 dB, and PSRR
is less than 1.8 µV/V. On-chip Zener zap trimming is used to
achieve the low input offset voltage of the OP400 and eliminates
the need for offset nulling. The OP400 conforms to the industrystandard quad pinout, which does not have null terminals.

The OP400 features low power consumption, drawing less than
725 µA p
er amplifier. The total current drawn by this quad
amplifier is less than that of a single OP07, yet the OP400 offers
significant improvements over this industry-standard op amp.
Voltage noise density of the OP400 is a low 11 nV/√Hz at
10 Hz, half that of most competitive devices.
The OP400 is pin-compatible with the LM148, HA4741,
RM4156, a
nd LT1014 operational amplifiers and can be used to
upgrade systems having these devices. The OP400 is an ideal
choice for applications requiring multiple precision operational
amplifiers and where low power consumption is critical.

APPLICATIONS
The OP400 is inherently stable at all gains and is capable of
driving large capacitive loads without oscillating. Nonetheless,
good supply decoupling is highly recommended. Proper supply
decoupling reduces problems caused by supply line noise and
improves the capacitive load-driving capability of the OP400.
Total supply current can be reduced by connecting the inputs of
n unused amplifier to V−. This turns the amplifier off,
a
lowering the total supply current.
DUAL LOW POWER INSTRUMENTATION AMPLIFIER
A dual instrumentation amplifier that consumes less than
33 mW of power per channel is shown in Figure 30. The linear-
ty of the instrumentation amplifier exceeds 16 bits in gains of 5 to
i
200 and is better than 14 bits in gains from 200 to 1000. CMRR
is above 115 dB (G = 1000). Offset voltage drift is typically
0.4 V/°C over the military temperature range, which is
comparable to the best monolithic instrumentation amplifiers.
The bandwidth of the low power instrumentation amplifier is
a function of gain and is shown in
The output signal is specified with respect to the reference
in
put, which is normally connected to analog ground. The
reference input can be used to offset the output from −10 V to
+10 V if required.

BIPOLAR CURRENT TRANSMITTER
In the circuit of Figure 31, which is an extension of the standard
three op amp instrumentation amplifier, the output current is
proportional to the differential input voltage. Maximum output
current is ±5 mA, with voltage compliance equal to ±10 V when
using ±15 V supplies. Output impedance of the current
transmitter exceeds 3 M, and linearity is better than 16 bits
with gain set for a full-scale input of ±100 µV.
DIFFERENTIAL OUTPUT INSTRUMENTATION AMPLIFIER
The output voltage swing of a single-ended instrumentation
amplifier is limited by the supplies, normally at ±15 V, to
a maximum of 24 V p-p. The differential output instrumentation amplifier shown in Figure 32 can provide an output voltage
swin
g of 48 V p-p when operated with ±15 V supplies. The
extended output swing is due to the opposite polarity of the
outputs. Both outputs swing 24 V p-p, but with opposite
polarity, for a total output voltage swing of 48 V p-p. The reference
input can be used to set a common-mode output voltage over the
range ±10 V. The PSRR of the amplifier is less than 1 µV/V with
CMRR (G = 1000) better than 115 dB. Offset voltage drift is
typically 0.4 µV/°C over the military temperature range.

MULTIPLE OUTPUT TRACKING VOLTAGE REFERENCE
Figure 33 shows a circuit that provides outputs of 10 V, 7.5 V, 5 V,
and 2.5 V for use as a system voltage reference. Maximum
output current from each reference is 5 mA with load regulation
under 25 μV/mA. Line regulation is better than 15 μV/V,
and output voltage drift is under 20 μV/°C. Output voltage
noise from 0.1 Hz to 10 Hz is typically 75 μV p-p from the
10 V output and proportionately less from the 7.5 V, 5 V, and
2.5 V outputs.
