LTC1276 General Description

The LTC1273/LTC1275/LTC1276 are 300ksps, sampling12-bit A/D converters that draw only 75mW from single5V or ±5V supplies. These easy-to-usedevices comecomplete with 600ns sample-and-holds, precision refer-ences and internally trimmed clocks. Unipolar and bipo-lar conversion modes provide flexibility for various appli-ations. They are built with LTBiCMOSTMswitched ca-pacitor technology.

These devices have 25ppm/°C (max) internal references.The LTC1273 converts 0V to 5V unipolar inputs from asingle 5V supply. The LTC1275/LTC1276 convert ±2.5Vand ±5V respectively from ±5V supplies. Maximum DCspecifications include ±1/2LSB INL, ±3/4LSB DNL and25ppm/°C full scale drift over temperature. OutstandingAC performance includes 70dB S/(N + D) and 77dB THDat the Nyquist input frequency of 150kHz.

The internal clock is trimmed for 2.7µs maximum conver-sion time. The clock automatically synchronizes to eachsample command eliminating problems with asynchro-nous clock noise found in competitive devices. A highspeed parallel interface eases connections to FIFOs, DSPsand microprocessors.
