AD7870KN

The AD7870KN is a complete 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices. It integrates a track-and-hold amplifier, an internal 3V buried Zener reference, and a laser-trimmed clock oscillator, requiring no external components for conversion timing. The device operates from ±5V analog and digital supplies and offers a single-ended input configuration with a sampling rate of 100k samples per second.

The ADC features a versatile data interface supporting both parallel and SPI serial output formats, with a 1:1 S/H:ADC ratio. The architecture is based on a SAR converter, providing high speed and accuracy for a wide range of applications. The on-chip reference ensures stable performance over the operating temperature range of 0°C to 70°C.

The AD7870KN is housed in a 24-pin DIP package (24-DIP, 0.300" width, 7.62mm body) with through-hole mounting, making it suitable for prototyping and industrial applications. The supplier device package is designated as 24-PDIP.

This component is part of the AD7870 series, which includes multiple input range options. The AD7870KN is designed for applications requiring precise analog-to-digital conversion with moderate speed and low power consumption, typical of 60mW.
