MAX1035EUP+

Analog To Digital Converters (ADC) Overview

The MAX1035EUP+ is a multirange, low-power, 14-bit successive-approximation analog-to-digital converter (ADC) operating from a single +5V supply. It features four single-ended or two true differential analog input channels, each independently software-programmable for seven single-ended ranges and three differential ranges. The device achieves throughput rates up to 115ksps and includes an on-chip +4.096V reference. It supports digital interfacing with 2.7V to 5.25V systems via an SPI-/QSPI-/MICROWIRE-compatible serial interface. Partial power-down mode reduces supply current to 1.3mA, while full power-down mode lowers it to 1µA. It is specified for operation from -40°C to +85°C in a 20-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer's marking and datasheet specifications against the ordered part number. Confirm that the package type matches the required 20-pin TSSOP configuration. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the electrical characteristics to ensure compatibility with the system's power supply and signal levels.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1035EUP+ when four single-ended or two differential analog inputs are required with 14-bit resolution. Consider this component for applications needing multirange input capabilities and ±6V fault tolerance. Evaluate the power consumption requirements, as the device offers partial and full power-down modes to minimize energy usage during idle periods. Ensure the system can accommodate the separate analog and digital supply voltages for optimal performance.

Analog To Digital Converters (ADC) Part Context

The MAX1035EUP+ belongs to the MAX1034/MAX1035 family of multirange, low-power, 14-bit ADCs. While the MAX1034 provides eight single-ended or four differential channels in a 24-pin TSSOP package, the MAX1035 offers four single-ended or two differential channels in a 20-pin TSSOP package. Both devices share similar electrical characteristics and functionality, differing primarily in the number of available analog input channels.
