LTC1402CGN#PBF

LTC®1402 is a 12bit, 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. Typical application includes telecommunications, high speed data and signal acquisition, digitally multiplexed data acquisition systems, digital radio receivers, spectrum analysis, low power and battery-operated systems, handheld or portable instruments, imaging systems.
