LT6375AHDF Equivalent & Substitute Parts

Part Overview

The LT6375AHDF is a differential amplifier integrated circuit manufactured by Analog Devices Inc., designed for rail-to-rail operation in a 14-DFN (4x4) surface mount package. This device is classified as obsolete, indicating it has been discontinued by the manufacturer and is no longer in active production. The LT6375AHDF operates across a wide supply voltage range of 3V to 50V with a slew rate of 2.4V/µs and -3dB bandwidth of 575 kHz, making it suitable for precision differential signal conditioning applications. Due to its obsolete status, identifying equivalent substitute parts is essential for design continuity, system maintenance, and procurement of replacement components for existing installations.

Functional Parameters:

  • Amplifier Type: Differential
  • Number of Circuits: 1
  • Output Type: Rail-to-Rail

Electrical Performance Parameters:

  • Slew Rate: 2.4V/µs
  • -3dB Bandwidth: 575 kHz
  • Current - Supply: 350µA
  • Current - Output / Channel: 28 mA
  • Voltage - Supply Span: 3V to 50V
  • Operating Temperature Range: -40°C to 125°C

Physical Parameters:

  • Mounting Type: Surface Mount
  • Package / Case: 14-WFDFN Exposed Pad, 12 Leads
