MAX1456CWI+

Sensor And Detector Interfaces Overview

The MAX145CWI+ is a low-power, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.7V to +5.25V supply and features a 7.4µs successive-approximation conversion time with an automatic power-down mode that reduces current to 0.2µA. The device includes an internal track-and-hold circuit and a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards. It accepts pseudo-differential inputs ranging from 0 to VREF and provides a sampling rate of up to 108ksps. The component is housed in an 8-pin µMAX package.

Sensor And Detector Interfaces Feature Summary

• Single-supply operation supporting voltage ranges from +2.7V to +5.25V
• Integrated track-and-hold circuitry for signal acquisition
• Compatible with standard serial interfaces including SPI, QSPI, and MICROWIRE
• Low power consumption with automatic shutdown capabilities

Sensor And Detector Interfaces Applications

• Battery-powered systems
• Portable data logging equipment
• Medical instruments
• Process-control monitoring systems

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'CWI+' against official documentation to confirm the commercial temperature range and SOIC-style packaging variant. Confirm RoHS compliance status through the manufacturer's latest product change notification or datasheet revision history before finalizing procurement plans.

Sensor And Detector Interfaces Selection Notes

Select this component when a pseudo-differential input configuration is required rather than the dual single-ended channels found in the MAX144 variant. Ensure the application can accommodate the 8-pin µMAX package dimensions and verify that the external reference voltage requirements align with the system design constraints.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX144/MAX145 family of low-power, 12-bit ADCs. While the MAX144 offers two single-ended channels, the MAX145 provides one pseudo-differential channel. Both share identical pinouts, power specifications, and serial interface protocols, allowing for flexible design choices based on input signal requirements.

Sensor And Detector Interfaces Replacement Considerations

The MAX144ACUA+ serves as a pin-compatible alternative within the same family, offering dual single-ended channels instead of pseudo-differential inputs. Verify functional compatibility regarding input multiplexing and software configuration before substituting.
