TIINA128P
Overview
The INA128P is a low-power, general-purpose instrumentation amplifier that offers excellent accuracy and a wide supply range of +/-2.25V to +/-18V. It features a versatile three-op-amp design, allowing gain to be set from 1 to 10,000 using a single external resistor. With a low quiescent current of 700uA and high input impedance, it is optimized for precision signal conditioning in industrial and medical environments.
Why Choose This Part
The INA128P provides a high bandwidth of 1.3 MHz and a fast slew rate of 4V/us, which is exceptional for a precision instrumentation amplifier. Its low offset voltage of 25 uV and low input bias current of 2 nA minimize errors in high-impedance sensor applications. The 8-PDIP package makes it easy to integrate into through-hole designs and breadboard prototypes.
Applications
Key Specifications
Getting Started
To use the INA128P, calculate the gain resistor value using the formula G = 1 + (50kOhm / Rg) and connect it between pins 1 and 8. Ensure proper power supply decoupling with 0.1uF ceramic capacitors placed close to the V+ and V- pins. For rapid prototyping, this 8-PDIP component can be used directly on a standard breadboard or with a DIP-to-SMD adapter if moving to surface mount layouts later.
