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 or dual ±5V supply with a maximum sampling rate of 250 kS/s per channel. The device utilizes a successive approximation architecture with a parallel interface and stores conversion results in an internal 8x8 RAM. Key electrical specifications include a typical integral nonlinearity error of ±1 LSB, a power dissipation of 696 mW at +70°C, and operation within a temperature range of 0°C to +70°C.

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 allows sequential data retrieval via read pulses.
• Supports flexible unipolar/bipolar and single-ended/differential input configurations.

Analog To Digital Converters (ADC) Applications

• Phase-sensitive data acquisition systems
• Vibration analysis and waveform monitoring
• DSP-based analog input interfaces
• AC power metering equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' for commercial temperature range and 'NG' for PDIP-24 packaging against current manufacturer documentation. Confirm RoHS compliance status as manufacturing practices may evolve. Check for obsolescence notices or lifecycle changes directly from Analog Devices/Maxim Integrated before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required without external multiplexers. Ensure the 8-bit resolution meets system accuracy requirements. Verify that the 250 kS/s throughput aligns with signal bandwidth needs. Consider the 2.5V internal reference stability if high precision is critical, or plan for an external reference if tighter tolerance is necessary.

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, differing primarily in channel count and package pinout availability.
