LTC1402CGN#PBF Product Details

The LTC1402CGN#PBF is a 12-bit, 2.2Msps sampling A/D converter. 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 a 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.

Outstanding AC performance includes 72dB S/(N + D) and –93dB SFDR at the Nyquist input frequency of 1.1MHz with dual ±5V supplies and –84dB SFDR with a single 5V supply.

The LTC1402CGN#PBF has two power saving modes: 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 (REFRDY) signal is available in the serial data word to indicate that the reference has settled and the chip is ready to convert.

The 3-wire serial port allows compact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs. A digital output driver power supply pin allows direct connection to 3V or lower logic.
