Instrumentation Amplifier INA121P

About this product

FET-input instrumentation amplifier (INA121P) housed in a standard 8-pin DIP package. Features extremely low input bias currents and high common-mode rejection, designed for amplifying low-level signals from bridge sensors and bio-potential electrodes. Gain is adjustable from 1 to 10,000 using a single external resistor.

Resistors, capacitors, transistors, diodes, ICs, connectors, wires and discrete components for any bench.
