LTC2325-16

Quad, 16-Bit, 5Msps/Ch

Simultaneous Sampling ADC

FEATURES

DESCRIPTION

The LTC^®2325-16 is a low noise, high speed quad 16-bit

successive approximation register (SAR) ADC with

differential inputs and wide input common mode range.

–88dB THD (Typ) at f = 2.2MHz

Guaranteed Operation to 125°C

Single 3.3V or 5V Supply

2.048V or 4.096V temperature-compensated reference.

The LTC2325-16 also has a high speed SPI-compatible

serial interface that supports CMOS or LVDS. The fast

5Msps per channel throughput with one cycle latency

makes the LTC2325-16 ideally suited for a wide variety

of high speed applications. The LTC2325-16 dissipates

only 40mW per channel and offers nap and sleep modes

to reduce the power consumption to 90μW for further

power savings during inactive periods.
