MAX192BCAP+

MAXIM INTEGRATED PRODUCTS  MAX192BCAP+  模数转换器, 低功率, 10 bit, 133 kSPS, 单, 4.75 V, 5.25 V, SSOP

The is a low power, 8-channel, serial 10bit ADC in 20 pin SSOP package. It is a low cost, 10bit data acquisition system that combines an 8-channel multiplexer, high bandwidth track/hold and serial interface with high conversion speed and ultra low power consumption. The analogue inputs are software configurable for single ended and differential unipolar/bipolar operation. The 4 wire serial interface connects directly to SPI, QSPI and Microwire devices without using external logic. A serial strobe output allows direct connection to TMS320 family digital signal processors. The MAX192 uses either the internal clock or an external serial interface clock to perform successive approximation A/D conversions. The serial interface can operate beyond 4MHz when the internal clock is used. The MAX192 has an internal 4.096V reference with a drift of ±30ppm typical. A reference buffer amplifier simplifies gain trim and two sub-LSBs reduce quantization errors.
