MAX172BCNG+

Analog To Digital Converters (ADC) Overview

The MAX172BCNG+ is a complete, monolithic 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes successive approximation register (SAR) architecture and operates with a single +5V power supply. The device features an internal reference voltage of 4.75 V and supports a sampling rate of 100 kS/s. It accepts single-ended inputs and provides parallel CMOS digital outputs. Key linearity specifications include differential nonlinearity (DNL) and integral nonlinearity (INL) both within +/- 1 LSB. The component is housed in a 24-pin PDIP package and is rated for operation between 0°C and +70°C, with a typical power dissipation of 215 mW.

• Battery-powered test equipment utilizing low-power ADCs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range (0°C to +70°C) and 'NG+' denotes lead-free PDIP-24 packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current lifecycle status as older Maxim parts may be subject to discontinuation or limited availability from authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required with minimal external circuitry due to the integrated reference. Ensure the system design accommodates parallel data bus connections rather than serial interfaces. Verify that the 100 kS/s throughput meets application bandwidth requirements and that the 215 mW power dissipation fits within the thermal constraints of the PDIP-24 enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX172B series of precision ADCs. It shares the same core architecture and pinout as variants like the MAX172ACNG+, differing primarily in linearity specifications and temperature ranges. The MAX172 family was designed to simplify high-resolution data conversion tasks in cost-sensitive applications compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX172ACNG+ serves as a functional alternative within the same package, offering tighter INL specifications (+/- 0.5 LSB) but potentially different thermal or pricing characteristics. Designers should verify electrical parameter compatibility before substitution.
