Description

The MAX1132BCAP is a 16-bit Analog to Digital Converter (ADC) model with a maximum sample rate of 200ksps. It features a serial interface that can directly connect to SPI™, QSPI™, and MICROWIRE™ devices without the need for external logic. The ADC combines an input scaling network, internal track/hold, clock, a +4.096V reference, and three general-purpose digital output pins in a compact 20-pin SSOP package. With its excellent dynamic performance, high-speed operation, and low power consumption, the MAX1132BCAP is ideal for industrial process control, instrumentation, and medical applications. It has a wide input voltage range of 0 to +12V (unipolar) or ±12V (bipolar).
