MAX11162EUB+

Analog To Digital Converters (ADC) Overview

The MAX11162EUB+ is a 16-bit, 500ksps SAR ADC with unipolar pseudo-differential inputs. It operates from a 4.75V to 5.25V analog supply (VDD) and a 2.3V to 5.25V digital supply (OVDD). The device achieves 93dB SNR and -105dB THD at 10kHz input frequency. Static performance includes ±0.2 LSB typical DNL and ±0.6 LSB typical INL, guaranteeing 16-bit no-missing codes. Power consumption is 23mW at full throughput, reducing to 10μA in shutdown mode. It communicates via SPI-compatible serial interfaces and is housed in a 10-pin µMAX package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official datasheet specifications. Confirm the package type matches the 10-pin µMAX format. Ensure the operating temperature range meets the required -40°C to +85°C specification for your application environment before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high precision is required for single-channel applications. It is suitable for systems needing a separate digital supply voltage ranging from 2.3V to 5V while maintaining a 5V analog supply. Consider the external reference requirement and source impedance limitations when designing the input stage for optimal settling time.

Analog To Digital Converters (ADC) Part Context

This part belongs to the 14-bit to 18-bit SAR ADC family from Analog Devices/Maxim Integrated. It shares architectural similarities with other devices in the series but is distinct in its specific 16-bit resolution, 500ksps throughput rate, and unipolar input configuration. It complements higher-speed or multi-channel variants within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11162EUB+ does not have a direct pin-to-pin replacement listed in the provided documentation. Designers should evaluate other members of the 14-bit to 18-bit SAR ADC family, such as the MAX11160 or MAX11164, if different input ranges or reference types are acceptable.

Analog To Digital Converters (ADC) FAQ

What is the maximum input voltage range for the AIN+ pin?

The AIN+ pin has an absolute input voltage range of -0.1V to (VDD + 0.1V), allowing it to measure signals up to VREF.

How is the serial interface mode selected?

The interface mode is determined by the logic level of the SDI pin during the rising edge of the CNVST signal. High selects CS mode, while low selects daisy-chain mode.

Does the MAX11162 include an internal reference?

No, the MAX11162 requires an external low-impedance reference source on the REF pin to achieve 16-bit accuracy.
