SP8527 - Micropower Sampling 10-Bit A/D Converter

Description

The SP8527 is a very low power 10-Bit A/D converter.

The SP8527 typically draws 230µA of supply current when sampling at 38.3 kHz.

Supply current drops linearly as the sample rate is reduced.

Features

  • The input sampling scheme is full differential, where the maximum full scale range is VREF. The signal is applied between +IN and -IN. The signals applied at each input may both be dynamic. This is in contrast with pseudo differential devices which must have input low held at a constant level during conversion. The converter will provide significant common mode rejection because of the full differential sampling. Each input independently must remain between ground and Vcc to avoid clamping the i.

® SP8527 Micropower Sampling 10-Bit A/D Converter s s s s s s s s s Low Cost 10-Bit Serial Sampling ADC Guaranteed +1.0 LSB Max INL 8-Pin NSOIC Plastic Package Low Power @ 230µA including Automatic Shutdown: 1nA (typ) Full differential input stage Single Supply 3.0V to 5.5V operation Digital Serial Interface Sample Rate: 26.1µS DESCRIPTION The SP8527 is a very low power 10-Bit A/D converter. The SP8527 typically draws 230µA of supply current when sampling at 38.3 kHz. Supply current drops linearly as the sample rate is reduced. The ADC automatically powers down when not performing conversions, drawing only leakage current. The SP8527 is available in 8-Pin NSOIC packages, specified over Commercial and Industrial temperature ranges.
