MAX1162ACUB+

Analog To Digital Converters (ADC) Overview

The MAX1162ACUB+ is a low-power, 16-bit analog-to-digital converter (ADC) featuring a successive-approximation register architecture. It operates with a single +5V analog supply and supports digital logic levels from +2.7V to +5.25V. The device achieves a maximum sampling rate of 200ksps with typical power consumption of 2.75mA at full speed. It incorporates an AutoShutdown mode that reduces current to less than 10µA. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 90dB, Integral Nonlinearity (INL) of ±2 LSB for the B-grade variant, and a Full-Power Bandwidth of 4MHz. The component utilizes a serial interface compatible with SPI, QSPI, and MICROWIRE standards.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade suffix (e.g., BCUB+) against project requirements, as INL accuracy varies between B and C grades. Confirm package availability, as DFN options may require factory contact. Ensure external reference components meet the specified impedance and bypassing criteria to maintain 16-bit performance.

Analog To Digital Converters (ADC) Selection Notes

Select the B-grade version for tighter linearity specifications requiring ±2 LSB INL. Ensure the application environment stays within the 0°C to +70°C operating range for this specific package variant. Verify that the system clock frequency does not exceed 4.8MHz to maintain timing integrity. Consider input buffering if source impedance exceeds recommended limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1162 family of 16-bit ADCs manufactured by Analog Devices / Maxim Integrated. It shares architectural similarities with other members like the MAX1162BCUB+, differing primarily in temperature ranges and accuracy grades. The µMAX-10 package provides a compact solution for space-constrained designs requiring high-resolution data conversion.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same series include the MAX1162BCUB+ for standard industrial temperature ranges. For extended temperature operations, consider the MAX1162BEUB+. Verify that any substitute maintains the required 16-bit resolution and 200ksps sampling rate.
