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 patible, 16-bit or twobyte parallel output port. A convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
