FEATURES

LTC1604

High Speed, 16-Bit, 333ksps

Sampling A/D Converter

with Shutdown

DESCRIPTION

The LTC

1604 is a 333ksps, 16-bit sampling A/D con-

verter that draws only 220mW from ±5V supplies. This

high performance device includes a high dynamic range

sample-and-hold, a precision reference and a high speed

parallel output. Two digitally selectable power shutdown

modes provide power savings for low power systems.

The LTC1604’s full-scale input range is ±2.5V. Outstand-

ing AC performance includes 90dB S/(N+D) and –100dB

THD at a sample rate of 333ksps.

The unique differential input sample-and-hold can acquire

single-ended or differential input signals up to its 15MHz

bandwidth. The 68dB common mode rejection allows

users to eliminate ground loops and common mode noise

by measuring signals differentially from the source.

The ADC has μP compatible,16-bit parallel output port.

There is no pipeline delay in conversion results. A separate

convert start input and a data ready signal (BUSY) ease

connections to FlFOs, DSPs and microprocessors.
