The LTC1867L is a 16-bit, eight-channel, 175-ksps, 3-V supply ADC that offers low power without compromising speed or linearity. It draws only 2.7 mW at full speed, which is roughly half the power of competing devices. The power automatically drops at reduced speeds, typically 0.9 mW at 50 ksps. This device maintains excellent DC performance providing 16 bits with no missing codes over temperature and ±3 LSB INL. The LTC1867L is ideal for low-power portable instrumentation, industrial process control, and medical applications.

The LTC1867L has an easy-to-use multiplexer and serial interface. The multiplexer allows any combination of single-ended inputs or differential inputs in either Unipolar mode (0 to 2.5 V) or Bipolar mode (±1.25 V). The accuracy of the ADC is independent of the shift clock frequency, allowing these parts to operate in optoisolation or low-power applications.

The device is also available in a 12-bit version (LTC1863L). Both are available in pin-compatible, 5-V supply versions (LTC1867/LTC1863) and narrow SSOP-16 packages that provide a pin-compatible family for performance/cost optimization in the end product. The LTC1867L and LTC1863L are available in the commercial and industrial temperature ranges.

The LTC1867L costs $7.75 and the LTC1863L costs $3.85 in 1,000-piece quantities.
