Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) MAX1111EPE+

The MAX1111EPE+ is a low-power, 8-bit, 4-channel analog-to-digital converter (ADC) designed for applications requiring efficient data acquisition. It operates on a single supply voltage ranging from 2.7V to 5.5V and consumes only 85µA while sampling at rates up to 50ksps. The device features a software-configurable input that supports both unipolar and bipolar modes, making it versatile for various signal types. The MAX1111 includes an internal track/hold circuit, a 2.048V reference, and a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards. It also offers a power-down mode that reduces supply current to 6µA at 1ksps, enhancing battery life in portable applications. The total unadjusted error is specified at ±1 LSB maximum, with a typical value of ±0.3 LSB, ensuring reliable performance. This ADC is suitable for a range of applications, including portable data logging, medical instruments, and solar-powered remote systems. The MAX1111EPE+ is packaged in a compact 16-pin QSOP format, making it ideal for space-constrained designs.
