AD574A is a 12-bit single-ended voltage input analog-to-digital converter with 12-bit resolution, 5V power supply voltage and 5V internal reference voltage. It can accept ±5V analog input signals.
This document is a technical datasheet for the Analog Devices AD574A family of 12-bit analog-to-digital converters (ADCs). It provides detailed electrical characteristics, including resolution, linearity error, temperature range, and power supply requirements for multiple model grades such as the AD574AJ through AD574AU.
The datasheet includes an ordering guide that correlates specific models with their maximum operating temperatures and guaranteed linearity errors. It also features a block diagram illustrating the internal architecture, pin configuration details, and absolute maximum ratings to ensure safe operation limits are understood.
| Resolution | 12 Bits |
|---|---|
| Linearity Error (Typical) | ±1/2 LSB |
| Operating Temperature Range (Standard Grades) | 0 °C to +70 °C |
| Internal Reference Voltage | 10.0 Volts |
The AD574AK, L, T, and U grades are guaranteed for a maximum nonlinearity of ±1/2 LSB.
The nominal value of a code width is equivalent to 1 least significant bit (LSB) of the full-scale range or 2.44 mV out of 10 volts.
