MAX11156ETC+

Analog To Digital Converters (ADC) Overview

The MAX11156ETC+ is an 18-bit, 500ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Analog Devices / Maxim Integrated. It features a true bipolar input range of ±5V and includes an internal reference voltage. The device operates on a single 5V supply with a minimum operating voltage of 4.75V and a maximum of 5.25V. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 94.6 dB and a power dissipation of 1.349 W. It utilizes a 3-Wire, QSPI, or SPI interface for communication. The component is housed in a TDFN-12 surface-mount package and supports differential or single-ended input types within an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ETC+' against the official datasheet to confirm the TDFN-12 package and lead-free status. Confirm RoHS compliance details directly from the manufacturer's documentation. Check current availability status as distribution channels may vary by region. Ensure the ordering information matches the exact part number required for design-in.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 500ksps speed are required with a bipolar ±5V input range. It is suitable for applications needing an internal reference to simplify board design. Compare SNR performance at specific frequencies if dynamic performance is critical. Ensure the system power supply remains within the 4.75V to 5.25V range for optimal operation.

Analog To Digital Converters (ADC) Part Context

The MAX11156 belongs to the MAX1115X/6X family of high-performance SAR ADCs. This series is designed for applications demanding high accuracy and low noise. The ETC+ variant specifically denotes the TDFN-12 package configuration. Related evaluation kits, such as the MAX1115X/6X EV kit, are available for testing the entire product line.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11154ETC+ is a related 18-bit, 500ksps SAR ADC in the same TDFN-12 package but typically features a unipolar input range rather than the true bipolar ±5V range of the MAX11156. Verify input requirements before substitution.
