MAX154ACWG

Analog To Digital Converters (ADC) Overview

The MAX154ACWG+ is a CMOS high-speed, 8-bit analog-to-digital converter (ADC) featuring four multiplexed analog input channels and an integrated 2.5V reference. It utilizes a half-flash architecture with a built-in track/hold circuit to eliminate external components. The device operates on a single +5V supply and provides parallel data outputs via latched three-state buffers for direct microprocessor interfacing. Key electrical specifications include a typical conversion time of 2.0µs, a maximum sampling rate of 400kS/s, and a total unadjusted error of ±1/2 LSB. It functions within a temperature range of 0°C to +70°C and is housed in a 24-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 2.5V internal reference and built-in track/hold function to form a complete data acquisition system without external support components.
• Employs a half-flash conversion technique using two 4-bit flash ADC sections to achieve 8-bit resolution with minimal comparator count.
• Features simplified digital interfaces allowing the ADC to appear as a memory location or I/O port, supporting both WAIT state and continuous read modes.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'WG' corresponds to the 24-pin Shrink Small-Outline Package (SSOP) configuration. Confirm that the 'C' grade meets the required accuracy specifications for your application, as it differs from the higher precision 'A' grade variants. Ensure compatibility with the 0°C to +70°C industrial operating temperature range before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a compact, single-supply solution is required for multi-channel signal digitization. The MAX154ACWG is suitable for systems needing up to 400kS/s aggregate throughput with low power consumption. Consider the ±1/2 LSB accuracy specification against system requirements; if tighter linearity is needed, evaluate the MAX154AEWG variant instead.

Analog To Digital Converters (ADC) Part Context

The MAX154ACWG belongs to the MAX154/MAX158 family of CMOS high-speed ADCs. While the MAX154 provides four analog inputs, the MAX158 variant offers eight channels. Both share identical core architectures, including the half-flash conversion method and integrated reference, differing primarily in channel count and pin assignments for the additional inputs.
