MAX1071ETC+

Analog To Digital Converters (ADC) Overview

The MAX1071ETC+T is a low-power, high-speed, serial-output, 10-bit analog-to-digital converter (ADC) operating at up to 1.5Msps. It features true-differential bipolar inputs for improved noise immunity and dynamic range. The device operates from a single +2.7V to +3.6V supply with an external reference and includes a separate logic supply (VL) for direct interfacing with +1.8V to VDD digital logic. Power consumption is minimized via partial and full power-down modes, reducing current to 1mA and 1µA respectively. It utilizes a standard SPI/QSPI/MICROWIRE interface and is housed in a 12-pin TQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging when sourcing this component. Confirm the 'ETC' designation corresponds to the extended temperature range of -40°C to +85°C. Ensure the specific part number matches the bipolar input variant required for the application design.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1071ETC+T over the MAX1070 variant when bipolar input voltage ranges are required, as the MAX1071 accepts inputs from -VREF/2 to +VREF/2. Ensure the system design accommodates the need for an external reference voltage on the REF pin. Verify that the source impedance of the analog input signal allows for the specified 125ns acquisition time.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1070/MAX1071 family of 10-bit ADCs manufactured by Analog Devices Inc./Maxim Integrated. The MAX1071 specifically denotes the bipolar input version, whereas the MAX1070 offers unipolar inputs. Both share identical performance characteristics regarding speed, power, and interface compatibility.
