MAXIM INTEGRATED / ANALOG DEVICES MAX148BCAP+ Datasheet & Stock

The MAX148BCAP+ is a +2.7V to +5.25V, low power, 8-channel, serial 10bit analogue to digital converter (ADC) in 20 pin SSOP package. This ADC use a successive-approximation conversion technique and input track/hold (T/H) circuitry to convert an analogue signal to a 10bit digital output at sample rate of 133Ksps. A flexible serial interface provides easy interface to microprocessors (μPs), device provide a hard-wired SHDN(complementary) pin and a software-selectable power-down and can be programmed to automatically shut down at the end of conversion. This device is used in data acquisition, pen digitizers and process control.




Operating temperature range from 0°C to 70°C

8-channel single ended or 4-channel differential inputs

SPI/QSPI/MICROWIRE/TMS320 compatible 4-wire serial interface
