LTC1605

16-Bit, 100ksps,

Sampling ADC

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.

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.
