Product Details

The LTC1605-1/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, precision reference, switched capacitor successive approximation A/D and trimmed internal 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.

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.
