INA240A2PW Application Field and Working Principle

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The INA240A2PW is a rail-to-rail micro power instrumentation amplifier designed to work with power line voltage sensing. It provides high common-mode rejection ratio (CMRR) of >100 dB over a very wide range of input voltages from as low as 10 volts to rail or ground. The device provides high feedback capacitance that can be used to reject high-frequency transients in the power line. The INA240A2PW also includes a high-speed comparator that can be used for over/under voltage protection applications.The device is composed of a high-powered precision gain stage, which amplifies the low biased signals, and a comparator that works as a low level signal speed guard. The amplifier has a high common-mode rejection ratio (CMRR) and is excellent for voltage sensing and protection applications in power regulation systems. It is designed to work with a wide range of input voltages up to the device rails. It is suitable for industrial and automotive applications.The power amplifier has a very low quiescent current, a programmable input offset voltage and high output current drive. It has an output short-circuit protection, open- loop gain and input common-mode range, which ensure robust operation and reliability in no load conditions. The device also features a low input noise, low distortion and fast transient response, which is essential for ac coupling and powering application.The output can drive a load of up to 1000mA and feature a over/under voltage protection. The output is regulated and can be regulated with floating supply as well. The comparator has a low reference voltage, which is programmable from 2.5 V to 12 V and offers +30 dB common-mode rejection ratio at a maximum ±5V level swing.The INA240A2PW has a wide operating temperature range from -40°C to +125°C, providing for a very reliable performance in different temperature environments. It is packaged in a 28-pin Plastic BWDFN package. In summary, the INA240A2PW is an ideal solution for industrial and automotive application that require a high common-mode rejection ratio (CMRR), programmable input offset voltage and a wide range of input voltages up to the device rails. The device also features excellent output current drive, open-loop gain and input common-mode range, all of which ensure a robust operation and high level of reliability in no load conditions. It is also capable of delivering a +30 dB common-mode rejection ratio for ±5V level swing.
