description
The TL V2221 is a single operational amplifier manufactured using the T exas Instruments Advanced LinCMOS
process. This device is optimized and fully specified for single-supply 3-V and 5-V operation. For this
low-voltage operation combined with micropower dissipation levels, the input noise voltage performance has
been dramatically improved using optimized design techniques for CMOS-type amplifiers. Another added
benefit is that this amplifier exhibits rail-to-rail output swing. The output dynamic range can be extended using
the TL V2221 with loads referenced midway between the rails. The common-mode input voltage range is wider
than typical standard CMOS-type amplifiers. To take advantage of this improvement in performance and to
make this device available for a wider range of applications, V
ICR
is specified with a larger maximum input offset
voltage test limit of ± 5 mV , allowing a minimum of 0-V to 2-V common-mode input voltage range for a 3-V power
supply .

The DBV package available in tape and reel only.
The Advanced LinCMOS process uses a silicon-gate technology to obtain input offset voltage stability with
temperature and time that far exceeds that obtainable using metal-gate technology . This technology also makes
possible input impedance levels that meet or exceed levels offered by top-gate JFET and expensive
dielectric-isolated devices.
The TLV2221, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for
high-impedance sources such as piezoelectric transducers. Because of the low power dissipation levels
combined with 3-V operation, this device works well in hand-held monitoring and remote-sensing applications.
In addition, the rail-to-rail output feature with single or split power supplies makes this device an excellent choice
when interfacing directly to analog-to-digital converters (ADCs). All of these features combined with its
temperature performance make the TLV2221 ideal for remote pressure sensors, temperature control, active
voltage-resistive (VR) sensors, accelerometers, hand-held metering devices, and many other applications.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

description (continued)
The device inputs and outputs are designed to withstand a 100-mA surge current without sustaining latch-up.
In addition, internal ESD-protection circuits prevent functional failures up to 2000 V as tested under
MIL-PRF-38535; however, care should be exercised when handling these devices as exposure to ESD may
result in degradation of the device parametric performance. Additional care should be exercised to prevent
V
DD +
supply-line transients under powered conditions. Transients of greater than 20 V can trigger the
ESD-protection structure, inducing a low-impedance path to V
DD –
/GND. Should this condition occur, the
sustained current supplied to the device must be limited to 100 mA or less. Failure to do so could result in a
latched condition and device failure.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought
below V
