数据手册.pdfLTC1272 - 12Bit, 3µs, 250kHz Sampling A/D Converter; Package: PDIP; Pins: 24; Temperature Range: 0°C to 70℃
DESCRIPTION
The LTC1272 is a 3µs, 12-bit, successive approximation sampling A/D converter. It has the same pinout as the
industry standard AD7572 and offers faster conversion time, on-chip sample-and-hold, and single supply operation. It uses LTBiCMOS switched-capacitor technology to combine a high speed 12-bit ADC with a fast, accurate sample-and-hold and a precision reference.
