MAX153EAP

Analog To Digital Converters (ADC) Overview

The MAX153EAP+ is an 8-bit analog-to-digital converter (ADC) utilizing a half-flash architecture to achieve a 1Msps throughput rate. It operates on a single +5V or dual ±5V supply, supporting both unipolar and bipolar input ranges. The device features a microprocessor-compatible parallel interface with latched three-state outputs, eliminating the need for external logic. A dedicated power-down pin reduces current consumption to approximately 1µA, with recovery from shutdown occurring in under 200ns. Key electrical specifications include a typical conversion time of 660ns, a full-power bandwidth of 1MHz, and a signal-to-noise plus distortion ratio of 45dB at 1Msps sampling.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package suffix for the MAX153EAP+, as datasheet ordering information lists MAX153EAP+ with SSOP packaging. Confirm RoHS compliance status indicated by the '+' suffix. Check availability through authorized distributors as lead times may vary based on manufacturing schedules.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX153EAP+ for applications requiring high-speed 8-bit conversion without external clocking. Ensure the system supports the required parallel interface timing. Consider the thermal dissipation limits if operating near the upper temperature range of -40°C to +85°C. Verify that the source impedance allows for adequate acquisition time within the specified constraints.

Analog To Digital Converters (ADC) Part Context

The MAX153 belongs to the Maxim Integrated family of high-speed ADCs designed for µP compatibility. It serves as a cost-effective solution for mid-range resolution applications where speed and low power are critical. The E-grade variant extends the operating temperature range to industrial levels compared to the C-grade commercial version.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 8-bit resolution, 1Msps speed, and 20-pin package type. Verify interface compatibility, particularly regarding the MODE pin functionality and three-state output requirements. Ensure voltage supply and reference configurations align with the new component's specifications.
