LTC1605

16-Bit, 100ksps,

Sampling ADC

DESCRIPTION

FEATURES

The LTC^®1605 is a 100ksps, sampling 16-bit A/D con-

verter that draws only 55mW (typical) from a single 5V

supply. This easy-to-use device includes sample-and-

hold, precision reference, switched capacitor successive

approximation A/D and trimmed internal clock.

■

Sample Rate: 100ksps

■

Single 5V Supply

■

Bipolar Input Range: ±10V

Power Dissipation: 55mW Typ

Integral Nonlinearity: ±2.0LSB Max

Guaranteed No Missing Codes

Signal-to-Noise Ratio: 86dB Typ

Operates with Internal or External Reference

Internal Synchronized Clock

28-Pin 0.3” PDIP, SSOP and SW Packages

Improved 2nd Source to ADS7805 and AD976

■

The LTC1605’s input range is an industry standard ±10V.

Maximum DC specs include ±2.0LSB INL and 16-bits no

missing codes over temperature. An external reference

can be used if greater accuracy over temperature is

needed.

The ADC has a microprocessor compatible, 16-bit or two

byte parallel output port. A convert start input and a data

ready signal (BUSY) ease connections to FIFOs, DSPs and

microprocessors.
