AD7850JP

ADCs/DACs - Special Purpose Overview

The AD7850JP is a monolithic, high-speed 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes LC2MOS technology to achieve a sampling rate of 100 kHz with an internal track-and-hold amplifier. The device features a serial interface compatible with SPI and microcontrollers, alongside parallel access options. It operates on a single +5V supply for both analog and digital sections, simplifying power requirements. Packaged in a 28-pin PLCC, it is designed for applications requiring moderate speed and resolution with low power consumption.

ADCs/DACs - Special Purpose Part Context

The AD7850 belongs to the AD787x family of successive approximation register (SAR) ADCs. It shares architectural similarities with the AD7870 and AD7875 but differs in package availability and specific interface configurations. The 'JP' suffix denotes the plastic leaded chip carrier package variant.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include the AD7870 and AD7875. Verify interface compatibility and package dimensions when substituting, as these variants may offer different packaging options or slight performance variations.
