Overview
The MAX1133BEAP+T is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This serially interfaced ADC is designed to connect directly to SPI™, QSPI™, and MICROWIRE™ devices without the need for external logic. It features a single-channel architecture with an input scaling network, internal track/hold, clock, and a +4.096V reference voltage. The device is packaged in a 20-pin SSOP package and is ideal for applications requiring high-speed, low-power, and precise analog-to-digital conversion.
