LTC1604

High Speed, 16-Bit, 333ksps

Sampling A/D Converter

with Shutdown

DESCRIPTION

FEATURES

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.

■

A Complete, 333ksps 16-Bit ADC

■

90dB S/(N+D) and –100dB THD (Typ)

■

Power Dissipation: 220mW (Typ)

■

No Pipeline Delay

■

No Missing Codes over Temperature

■

Nap (7mW) and Sleep (10µW) Shutdown Modes

■

Operates with Internal 15ppm/°C Reference

or External Reference

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.

■

True Differential Inputs Reject Common Mode Noise

5MHz Full Power Bandwidth

±2.5V Bipolar Input Range

36-Pin SSOP Package

Theuniquedifferentialinputsample-and-holdcanacquire

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.

APPLICATIONS

■

Telecommunications

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

Thereisnopipelinedelayinconversionresults. Aseparate

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

connections to FlFOs, DSPs and microprocessors.
