Overview
The LTC2601IDD#PBF is a precision 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It is part of the LTC2601/LTC2611/LTC2621 family, which includes single 16-, 14-, and 12-bit rail-to-rail voltage output DACs. These DACs are housed in a compact 10-lead DFN package and are known for their high performance output buffers and guaranteed monotonicity. The LTC2601 series sets new benchmarks for board density and performance standards in single-supply, voltage-output DACs.
