MAX158BCAI+

Analog To Digital Converters (ADC) Overview

The MAX158BCAI+ is an 8-bit, 8-channel analog-to-digital converter (ADC) from the MAX154/MAX158 family. It features a half-flash architecture with a built-in track/hold and a 2.5V internal reference. The device operates on a single +5V supply with an analog input range of 0V to +5V. Key electrical parameters include a typical conversion time of 2µs, a maximum sampling rate of 400kS/s, and a total unadjusted error of ±1 LSB for the 'B' grade. It utilizes a parallel CMOS interface with latched three-state outputs and is housed in a 28-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel analog multiplexer, track/hold circuit, and 2.5V voltage reference into a single chip.
• Employs a half-flash conversion technique using two 4-bit flash ADC sections to achieve 8-bit resolution.
• Features latched, three-state data outputs that allow direct connection to microprocessor buses without external logic.

Analog To Digital Converters (ADC) Applications

• Digital Signal Processing
• High-Speed Data Acquisition
• Telecommunications
• High-Speed Servo Control
• Audio Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CAI+' corresponds to the commercial temperature range (0°C to +70°C), SSOP-28 package, and ±1 LSB accuracy grade. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the source document matches the manufacturer's official datasheet for the MAX154/MAX158 series to validate pinout and electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel, 8-bit high-speed acquisition system is required without external track/hold or reference components. The MAX158 provides eight channels, whereas the MAX154 offers four. Consider the 'C' suffix for commercial temperature ranges and 'E' for extended ranges. Verify that the parallel interface and +5V single-supply operation align with the system design constraints.

Analog To Digital Converters (ADC) Part Context

The MAX158BCAI+ belongs to the MAX154/MAX158 series of CMOS high-speed ADCs. This family combines analog multiplexers, converters, and references to simplify data acquisition systems. The MAX158 specifically provides eight analog input channels, distinguishing it from the four-channel MAX154 variant within the same architectural framework.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing MAX154/MAX158 variants based on channel count, accuracy grade, and package type.
