Product Introduction

Overview

The THS4532IPWR is a dual, ultra-low power, fully-differential amplifier produced by Texas Instruments. This device is designed for low-power data acquisition systems and high-density applications where power consumption and dissipation are critical. It operates with a supply voltage range of 2.5 V to 5.5 V and features a quiescent operating current of 250 µA per channel. The THS4532IPWR is characterized by its rail-to-rail output and input common-mode range below the negative rail, making it suitable for a variety of differential signal conditioning applications.

Key Features

  • Ultra Low Power: Quiescent operating current of 250 µA per channel and power-down mode current of 0.5 µA.
  • Fully-Differential Architecture: Allows for accurate output common-mode control, enabling dc coupling when driving analog-to-digital converters (ADCs).
  • Rail-to-Rail Output (RRO): Output voltage range extends to the supply rails.
  • Negative Rail Input (NRI): Input common-mode range extends below the negative supply rail.
  • High DC Accuracy: Low input offset voltage (±100 µV) and low input offset voltage drift (±3 µV/°C).
  • Wide Bandwidth and High Slew Rate: Small-signal bandwidth of 36 MHz and slew rate of 200 V/µs.
  • Output Common-Mode Control: Allows for precise control of the output common-mode voltage.

Applications

  • Low-Power SAR and ΔΣ ADC Drivers: Ideal for driving successive-approximation register (SAR) and delta-sigma (ΔΣ) analog-to-digital converters.
  • Differential to Differential Amplifier: Converts single-ended signals to differential signals.
  • Single-Ended to Differential Amplifier: Converts single-ended inputs to differential outputs.
  • Low-Power, Wide-Bandwidth Differential Driver: Suitable for driving differential signals in low-power, high-bandwidth applications.
  • High Channel Count and Power Dense Systems: Used in systems requiring multiple channels with low power consumption.
