LTC1605-1/LTC1605-2

Single Supply 16-Bit, 100ksps,

Sampling ADCs

FEATURES

DESCRIPTIO

The LTC^®1605-1/LTC1605-2 are 100ksps, sampling

16-bit A/D converters that draw only 55mW (typical) from

a single 5V supply. These easy-to-use devices include a

sample-and-hold, precisionreference, switchedcapacitor

successiveapproximationA/Dandtrimmedinternalclock.

■

Sample Rate: 100ksps

■

Complete 16-Bit Solution on a Single 5V Supply

■

Unipolar Input Range: 0V to 4V (LTC1605-1)

Bipolar Input Range: ±4V (LTC1605-2)

Power Dissipation: 55mW Typ

■

Signal-to-Noise Ratio: 86dB Typ

Operates with Internal or External Reference

Internal Synchronized Clock

The LTC1605-1’s input range is 0V to 4V while the

LTC1605-2’s input range is ±4V. An external reference

can be used if greater accuracy over temperature is

needed.

28-Pin 0.3" PDIP and SSOP Packages

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.
