MAX13021ASA+

Drivers, Receivers, Transceivers Overview

The MAX1302ASA+ is a multirange, low-power, 16-bit successive-approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and achieves throughput rates up to 115ksps. The device features eight single-ended or four true differential analog input channels, each independently software programmable for multiple unipolar and bipolar ranges. An on-chip +4.096V reference is available, with support for external references between 3.800V and 4.136V. It utilizes an SPI-/QSPI™-/MICROWIRE®-compatible serial interface and includes partial and full power-down modes for current reduction. The component is housed in a 24-pin TSSOP package and is specified for operation from -40°C to +85°C.

Drivers, Receivers, Transceivers FAQ

What are the supported analog input ranges?

Each channel supports seven single-ended ranges (0V to +VREF/2, -VREF/2 to 0V, 0V to +VREF, -VREF to 0V, ±VREF/4, ±VREF/2, and ±VREF) and three differential ranges (±VREF/2, ±VREF, and ±2 x VREF).

How does the device handle power consumption?

Partial power-down mode reduces supply current to 1.3mA typical, while full power-down mode reduces it to 1µA typical.

Is the input fault-tolerant?

Yes, all analog input channels are fault tolerant to ±6V without affecting the conversion results of other channels.
