MAX188BEAP+

The MAX188BEAP+ is a low power, 8 channel, serial 12bit analogue to digital converter in 20 pin SSOP package. It is a 12bit data acquisition system that combines an 8 channel multiplexer, high bandwidth track/hold and serial interface together with high conversion speed and ultra low power consumption. The analogue inputs are software configurable for unipolar/bipolar and single ended/differential operation. The 4 wire serial interface directly connects to SPI, QSPI and MICROWIRE devices without external logic. A serial strobe output allows direct connection to TMS320 family digital signal processors. It 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. It provides a hard wired complementary SHDN pin and two software selectable power down modes.

• 8 channel single ended or 4 channel differential inputs
• Operating temperature range from -40°C to 85°C
• Single +5V or ±5V operation
• Low power of 1.5mA in operating mode and 2μA in power down mode
• Requires an external reference
• Sampling rate is 133KSPS
• Reference buffer amplifier simplifies gain trim
• Total harmonic distortion is -80dB
