Product Details

The LTC1605 is a 100ksps, sampling 16-bit A/D converter 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.

Input Voltage Range
LTC1605 Bipolar ±10V
LTC1605-1 Unipolar 0V to 4V
LTC1605-2 Bipolar ±4V
