SD2142ET-12

12-bit, 65MHz, Dual Channel ADC

Overview & Features

The SD2142ET is a dual-channel, 12-bit, analog-to-digital converter (ADC) supporting sampling rates up to 65MSps. The
SD2142ET supports an extended temperature range of -55°C to 125°C. The device uses a multistage pipeline
architecture to achieve high signal-to-noise ratio (SNR) and linearity, over wide input signal bandwidth. The SD2142ET
can be set to operate using either CMOS or LVDS output interface. Programming for configuration and control is
accomplished using a 4-wire SPI-compatible serial bus. The digital output data can be programmed to be delivered in
offset binary, twos complement format, or gray code.
