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 twobyte parallel output port.
A convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
