MAX192BEAP+

The MAX192BEAP+ 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.

• Supply voltage range is 4.75V to 5.25V
• Operating temperature range from -40°C to 85°C
• 8-channel single ended or 4-channel differential inputs
• Low power consumption of 1.5mA (operating) and 2μA (power-down)
• Internal track/hold circuitry and sampling rate is 133KHz
• Relative accuracy is ±1LSB
