LTC1605
16-Bit, 100ksps,
Sampling ADC
DESCRIPTIO
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 LTC1605âs 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.
