MAX158BCPI

Analog To Digital Converters (ADC) Overview

The MAX158BCPI is a CMOS high-speed 8-bit analog-to-digital converter (ADC) featuring an integrated multiplexer and reference. It provides eight analog input channels with a conversion time of 2.5µs per channel. The device operates from a single +5V supply and includes a built-in track/hold function, eliminating the need for external components. It features a 2.5V on-chip reference and latched three-state data outputs for direct microprocessor interface. The total unadjusted error is specified at ±1 LSB for this variant, which supports Mode 0 and Mode 1 digital interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPI to confirm the accuracy class and package type against project requirements. Ensure the operating temperature range matches the industrial specification. Confirm pin compatibility with existing PCB layouts before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous or sequential analog inputs are required within a compact footprint. The integrated reference and track/hold simplify circuit design compared to discrete solutions. Verify that the source impedance meets the settling time requirements for the desired sampling rate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of high-speed ADCs. The MAX158 variant specifically offers eight input channels, whereas the MAX154 provides four. Both share identical core conversion architecture and interface protocols, differing primarily in channel count and pinout configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other MAX158 variants such as MAX158ACPI or MAX158AEPI, depending on the required accuracy and temperature range. Cross-family alternatives may require significant schematic redesign due to interface differences.
