Description

Product Overview

The OPA2170AIDCUR from Texas Instruments is a precision, low-noise, rail-to-rail output dual operational amplifier with 3MHz GBW and ±100µV offset voltage. Operating from 4V to 36V supply, it features 8nV/√Hz noise and 10pA bias current in a VSSOP-8 (2.3x2mm) package.

Key Specifications

Supply Range 4V – 36V (±2V to ±18V)
Offset Voltage ±100µV (typ), ±500µV (max)
Gain Bandwidth Product 3MHz
Slew Rate 1.5V/µs
Input Noise 8nV/√Hz @1kHz
Input Bias Current 10pA (typ)
Supply Current 1.5mA per amplifier
Operating Temperature -40°C to +125°C
Package VSSOP-8 (DCU, 2.3x2mm)

Features

  • Ultra-low offset voltage of ±100µV for precision applications
  • Rail-to-rail output for maximum dynamic range
  • 8nV/√Hz low noise for sensitive signal conditioning
  • 10pA bias current suitable for high-impedance sensors
  • Wide 4V-36V supply range for single or dual supply
  • EMI-filtered inputs for industrial noise immunity

Applications

  • Precision instrumentation and measurement
  • Medical equipment signal conditioning
  • Transimpedance amplifiers for photodiodes
  • Bridge sensor and strain gauge interfaces

The OPA2170AIDCUR is a precision, low-noise, rail-to-rail output dual operational amplifier from Texas Instruments. Combining ±100µV offset voltage, 8nV/√Hz input voltage noise, and 10pA bias current, it delivers outstanding precision for signal conditioning in measurement and medical applications. The rail-to-rail output stage maximizes dynamic range, while the 4V-36V supply range supports both single-supply and split-supply configurations.

The OPA2170AIDCUR uses a complementary bipolar input stage with chopper-free architecture to achieve ±100µV typical offset voltage without the clock noise associated with zero-drift amplifiers. The rail-to-rail output stage uses a common-emitter configuration that swings to within millivolts of the supply rails, maximizing output dynamic range. The 3MHz gain bandwidth and 1.5V/µs slew rate provide adequate bandwidth for precision signal conditioning up to the 100kHz range. EMI filtering on the inputs rejects high-frequency interference common in industrial environments.
