MAX1070ETC

Analog To Digital Converters (ADC) Overview

The MAX1070ETC is a low-power, high-speed, serial-output, 10-bit analog-to-digital converter (ADC) operating at sampling rates up to 1.5Msps. It features true-differential inputs for improved noise immunity and dynamic range. The device utilizes a standard SPI-compatible 3-wire serial interface and operates from a single +2.7V to +3.6V supply. It includes partial and full power-down modes, reducing current to 1mA (typ) and 1µA (max), respectively. A separate VL input allows direct interfacing with +1.8V digital logic. DC accuracy is specified at ±0.5 LSB INL, with typical power dissipation of 18mW.

• Base-station equipment

Analog To Digital Converters (ADC) Part Context

The MAX1070ETC belongs to the MAX1070/MAX1071 family of ADCs. While the MAX1070 specifies a unipolar analog input, the MAX1071 variant offers bipolar input capability. Both share identical performance characteristics regarding speed, power consumption, and interface protocols, differing primarily in input voltage range configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1071ETC serves as a functional substitute within the same package and specification profile, distinguished by its support for bipolar analog inputs rather than the unipolar input found on the MAX1070.
