MAX156BCNG+

Analog To Digital Converters (ADC) Overview

The MAX156BCNG+ is an 8-bit, 4-channel analog-to-digital converter (ADC) featuring simultaneous track-and-hold inputs and a 2.5V internal reference. It operates from a single +5V supply or dual ±5V supplies, supporting unipolar and bipolar input ranges with single-ended or differential configurations. The device utilizes a successive approximation architecture with a 3.6µs conversion time per channel. Data is stored in an internal 8x8 RAM and accessed via a parallel interface. It is housed in a 24-pin narrow PDIP package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all channels eliminates timing skew between input samples.
• Integrated 2.5V voltage reference reduces external component count.
• Internal 8x8 RAM stores conversion results for sequential access.
• Flexible configuration supports mixed single-ended and differential input modes.

Analog To Digital Converters (ADC) Applications

• Phase-sensitive data acquisition systems
• Vibration analysis and waveform monitoring
• DSP analog front-ends
• AC power metering equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCNG against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as manufacturing sources may vary. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required to prevent inter-channel phase errors. Ensure the system accommodates the 24-pin PDIP footprint. Verify that the 8-bit resolution and 250 kS/s aggregate throughput meet the application's dynamic range and speed requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX155/MAX156 family of high-speed multichannel ADCs. The MAX156 variant specifically provides four analog input channels, whereas the MAX155 offers eight. Both share identical core architectures, including the simultaneous track-and-hold circuitry and internal reference generation capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package are limited due to the specific simultaneous T/H architecture. Review the MAX155 series for expanded channel counts or newer Maxim Integrated ADC families for improved performance metrics.
