Product Summary

The LTC1861IMS#TRPBF is a 16-bit A/D converter that is offered in MSOP and SO-8 packages and operate on a single 5V supply. At 250ksps, the supply current is only 850μA. The supply current drops at lower speeds because the LTC1861IMS#TRPBF automatically power down between conversions. The 16-bit switched capacitor successive approximation ADC includes sample-and-holds. The LTC1865LAIMS#PBF offers a software-selectable 2-channel MUX and an adjustable reference pin on the MSOP version. The applications of the LTC1861IMS#TRPBF include High Speed Data Acquisition, Portable or Compact Instrumentation, Low Power Battery-Operated Instrumentation and Isolated and/or Remote Data Acquisition.
