INA121PA TI Instrumentation, OP Amps, Buffer Amps

The INA121PA is a low-power, FET-input instrumentation amplifier from Texas Instruments featuring ultra-low input bias current of 1 pA (max). It operates over a wide supply range of ±2.25V to ±18V and offers a gain setting range from 1 to 10,000 using a single external resistor. The device provides a gain bandwidth product of 600 kHz at G=10 and high common-mode rejection. Housed in an 8-pin PDIP package, it operates over -40°C to 85°C. Applications include high-impedance sensor interfaces, photodiode amplifiers, medical instrumentation, and industrial process control requiring very low input bias current.
