SP8537 - Micropower Sampling 10-Bit A/D Converter

Datasheet Summary

Description

The SP8537 is a very low power 10-Bit data acquisition chip.

TheSP8537 typically draws 250µA of supply current when sampling at 29.5 kHz.

Supply current drops linearly as the sample rate is reduced.

Features

  • Two program bits, which are shifted into the device prior to conversion, determine the input configuration. In the single ended MUX configuration the input signal will be applied to either channel 0 or channel 1 and will be ground referenced. The maximum full scale range is VCC. In the full differential mode, the signal will be applied between channel 0 and channel 1. The signals applied at each input may both be dynamic. This is in contrast with pseudo differential devices which must have input.

® SP8537 Micropower Sampling 10-Bit A/D Converter s s s s s s s s Low Cost 10-Bit Serial Sampling ADC 8-Pin NSOIC Plastic Package Low Power @ 250µA including Automatic Shutdown: 1nA(typ) Programmable Input Configuration: Full differential or 2 channel single-ended Single Supply 3.0V to 5.5V operation Half Duplex Digital Serial Interface Sample Rate: 33.9µS DESCRIPTION The SP8537 is a very low power 10-Bit data acquisition chip. TheSP8537 typically draws 250µA of supply current when sampling at 29.5 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 SP8537 is available in 8-Pin NSOIC packages, specified over Commercial, Industrial and Extended temperature ranges.
