Product Overview

The LTC1402CGN#PBF is a serial 12-bit sampling Analog-to-digital Converter (ADC) with shutdown. This high performance device includes a high dynamic range sample-and-hold and a precision reference. It operates from a single 5V supply or dual ±5V supplies and draws only 90mW from 5V. The versatile differential input offers unipolar range of 4.096V and a bipolar range of ±2.048V for dual supply systems where high performance op amps perform best, eliminating the need for special translation circuitry. The high common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. It has two power saving modes of nap and sleep. Nap mode consumes only 15mW of power and can wake up and convert immediately. In sleep mode, it typically consumes 10µW of power. Upon power-up from sleep mode, a reference ready signal is available in the serial data word to indicate that the reference has settled and the chip is ready to convert.
  • No missing codes over temperature
  • True differential inputs reject common mode noise
  • Internal reference can be overdriven externally
  • 3-wire interface to DSPs and processors
