MAX158BCPI+

Analog To Digital Converters (ADC) Overview

The MAX158BCPI+ is an 8-bit CMOS analog-to-digital converter featuring eight multiplexed analog input channels. It operates from a single +5V supply and includes an internal 2.5V reference, eliminating the need for external components. The device utilizes a half-flash architecture with a built-in track/hold function, achieving a typical conversion time of 2µs per channel. Data outputs are latched three-state buffers compatible with microprocessor buses. It supports parallel interface control via Chip Select (CS) and Read (RD) signals in two modes: Mode 0 for processors with WAIT states and Mode 1 for continuous operation without WAIT states.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component designation matches the specific package type and temperature range required for the application. Confirm that the ordering suffix corresponds to the desired accuracy grade and physical footprint. Ensure compatibility with existing board layouts regarding pin configurations and power supply requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with multiple analog inputs is required within a compact form factor. Consider the internal reference and track/hold features to reduce external component count. Evaluate the operating temperature range against environmental conditions. Verify that the microprocessor interface timing aligns with either Mode 0 or Mode 1 operational requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of high-speed multi-channel ADCs. The MAX158 variant specifically provides eight analog input channels compared to the four channels found in the MAX154. Both devices share similar architectural features including the half-flash conversion technique and integrated reference, differing primarily in channel count and package options.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other parts within the MAX154/MAX158 series such as the MAX158ACPI+ or MAX158BEPI+, depending on the required accuracy grade and operating temperature range. Ensure the replacement maintains the same 28-pin DIP package and electrical characteristics.
