MAX1062BCUB+T

Analog To Digital Converters (ADC) Overview

The MAX1062BCUB+T is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) housed in a 10-pin µMAX package. 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. Integral Nonlinearity (INL) is specified at ±2 LSB for the BCUB variant. Key electrical parameters include a Signal-to-Noise Ratio (SNR) of 84 dB, Differential Nonlinearity (DNL) of ±1 LSB, and a full-power bandwidth of 4 MHz. Shutdown current is less than 10µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'B' grade designation corresponds to the required ±2 LSB INL specification for your application accuracy needs. Ensure the operating temperature range aligns with the commercial grade limits defined in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 14-bit resolution and 200ksps throughput are required in a compact surface-mount package. Consider the BCUB variant if ±2 LSB INL meets system linearity requirements. Evaluate the need for external reference buffering based on the REF pin's DC load current requirements during conversion cycles.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1062 family of 14-bit ADCs. Variants such as ACUB and CCUB offer different INL specifications of ±1 LSB and ±3 LSB respectively. The EUB suffix denotes an extended industrial temperature range (-40°C to +85°C), whereas the CUB suffix is limited to the commercial range (0°C to +70°C).

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes within the same family include MAX1062ACUB+T and MAX1062CCUB+T for different linearity grades. For extended temperature operation, consider MAX1062AEUB+T or MAX1062CEUB+T. Verify pin compatibility and software interface timing before substitution.
