MAX122ACNG

Analog To Digital Converters (ADC) Overview

The MAX122ACNG is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a successive approximation register (SAR) architecture and features a parallel data interface for single-ended input signals. The device operates within a temperature range of 0°C to +70°C and is housed in a 24-pin Plastic Dual In-Line Package (PDIP-24). Key electrical specifications include a sampling rate of 333 kS/s, an internal reference voltage of 5 V, and a maximum power dissipation of 640 mW. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at +/- 0.75 LSB, with a signal-to-noise ratio (SNR) of 70 dB.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with SAR architecture

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CNG' against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the current datasheet or component certification documents, as regulatory status may vary between production lots.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and parallel interface are required for single-ended signals. Ensure the design accommodates the 24-pin PDIP footprint and operates within the 0°C to +70°C commercial temperature range. Verify that the system power supply can support the 640 mW power dissipation requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX122A series of high-speed, low-power ADCs. It shares architectural similarities with other members of the family but is distinguished by its PDIP-24 through-hole packaging and commercial temperature rating compared to surface-mount or industrial-grade variants.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the manufacturer's obsolescence notices or cross-reference guides for verified substitute part numbers. Do not assume functional compatibility with other packages or temperature grades without verifying pinout and electrical parameter alignment.
