MAX174CCPI+

Analog To Digital Converters (ADC) Overview

The MAX174CCPI+ is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes successive approximation register (SAR) architecture and features an internal buried zener voltage reference providing 10V output. The device operates with single-ended inputs, supporting unipolar ranges of 0 to +10V or 0 to +20V, and bipolar ranges of ±5V or ±10V via pin strapping. It employs a parallel interface compatible with 8-, 12-, and 16-bit microprocessor buses. Power requirements include VCC (+12V/+15V), VEE (-12V/-15V), and VL (+5V). The component is housed in a 28-pin PDIP package and supports a maximum conversion time of 25μs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) and 'P' denotes the plastic DIP package. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure supply voltages match the required ±12V/±15V and +5V rails before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a complete 12-bit ADC with integrated reference and clock is required without external components. Consider the 25μs conversion speed and parallel interface constraints. Verify that the 28-pin PDIP footprint fits the PCB layout and that the operating temperature range meets environmental specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX174/MX574A/MX674A family of industry-standard 12-bit ADCs. The MAX174 variant offers the fastest conversion speed at 8μs, while the MX574A and MX674A provide slower speeds of 15μs and 25μs respectively. All share identical pinouts and functional architectures.

Analog To Digital Converters (ADC) Replacement Considerations

MX574AKPI+ and MX674AJPI+ are functionally compatible within the same family, differing primarily in conversion speed and accuracy grades. Direct replacement requires verifying that the speed and linearity specifications meet the design requirements.
