Overview
The MAX1309ECM/V+ is a 12-bit, analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–MAX1314 family, which offers high-performance simultaneous sampling capabilities. The MAX1309ECM/V+ is available in a 48-pin 7mm x 7mm LQFP package and operates over an extended temperature range of -40°C to +85°C.
This ADC provides up to eight, four, or two independent input channels, each with independent track-and-hold (T/H) circuitry for simultaneous sampling. It is designed for applications requiring high throughput and precision in various input ranges.
