LTC1865L

The LTC^®1865L is a 16-bit A/D converter that is offered in MSOP and SO-8 packages and operates on a single 3V supply. At 150ksps, the supply current is only 450A. The supply current drops at lower speeds because the LTC1865L automatically powers down to a typical supply current of 1nA between conversions. This 16-bit switched capacitor successive approximation ADC includes a sample-and-hold. The LTC1865L offers a software-selectable 2-channel MUX. An adjustable reference pin is provided on the MSOP version.

The 4-wire, serial I/O, MSOP or SO-8 package and extremely high sample rate-to-power ratio make this ADC an ideal choice for compact, low power, high speed systems.

This ADC can be used in ratiometric applications or with external references. The high impedance analog inputs and the ability to operate with reduced spans down to 1V full scale, allow direct connection to signal sources in many applications, eliminating the need for external gain stages.
