MAX1162AEUB+

Analog To Digital Converters (ADC) Overview

The MAX1162AEUB+ is a low-power, 16-bit successive-approximation analog-to-digital converter (ADC) in a 10-pin µMAX package. It operates with a single +5V analog supply and supports digital logic voltages from +2.7V to +5.25V. The device achieves a maximum sampling rate of 200ksps with typical current consumption of 2.75mA at full speed. It features an internal track-and-hold circuit with a 4MHz input bandwidth and requires an external reference voltage between +3.8V and AVDD. The serial interface is compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes across the operating temperature range
• Single +5V analog supply operation with adjustable digital logic levels
• Internal track-and-hold circuitry providing a 4MHz small-signal input bandwidth
• AutoShutdown mode reduces supply current to less than 10µA

Analog To Digital Converters (ADC) Applications

• Motor Control systems
• Industrial Process Control
• Data-Acquisition Systems
• Thermocouple Measurements
• Portable and Battery-Powered Equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix AEUB+ corresponds to the -40°C to +85°C industrial temperature range and 10-pin µMAX package configuration. Confirm that the required external reference voltage falls within the specified +3.8V to AVDD input range for proper ADC operation. Ensure the digital interface timing meets the minimum setup and hold requirements for the selected microcontroller clock speed.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit accuracy and high-speed conversion are required in space-constrained designs. The separate analog and digital supplies facilitate direct interfacing with lower-voltage digital logic without level shifters. Consider the input buffer requirements if the source impedance exceeds 1kΩ or if multiplexing multiple channels to ensure adequate settling time during the acquisition phase.

Analog To Digital Converters (ADC) Part Context

The MAX1162 belongs to Maxim Integrated's family of low-power, high-resolution SAR ADCs designed for battery-operated applications. It shares architectural similarities with other devices in the series but is distinguished by its specific +5V analog supply requirement and 200ksps throughput capability. The µMAX package provides a compact footprint suitable for dense PCB layouts.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives include the MAX1162BCUB+ for commercial temperature range applications. Higher-performance upgrades within the same form factor may include the MAX11168EUB+, which offers 16-bit resolution at 500ksps with an internal reference.
