Introduction

AI Translation

The ADS79xx is a family of 12/10/8-bit pin-compatible multi-channel analog-to-digital converters (ADCs). These devices incorporate a capacitor-based successive approximation register (SAR) ADC with inherent sample-and-hold. They accept a wide analog power supply range from 2.7V to 5.25V. The extremely low power consumption makes these devices suitable for battery-powered and isolated power supply applications. A wide I/O power supply range from 1.7V to 5.25V enables these devices to interface seamlessly with the most common digital hosts. To facilitate connection to microcontrollers and digital signal processors (DSPs), this output is controlled by CS and SCLK. This input signal is sampled on the falling edge of CS. It uses SCLK for conversion, serial data output, and reading serial data. These devices can also perform automatic sequencing of preselected channels or manually select channels for the next conversion cycle. There are two software-selectable input ranges (0V to VREF and 0V to 2×VREF), independently configurable general-purpose input/output (GPIO) pins (4 for TSSOP and 1 on devices with VQFN packages), and two programmable alarm thresholds per channel. These features make these devices suitable for most data acquisition applications. These devices have a powerful power-down feature. This feature is very helpful for energy saving when the devices operate at lower conversion speeds. The 16-channel and 12-channel devices in this family are available in 38-pin TSSOP and 32-pin VQFN packages, while the 4/8-channel devices are available in 30-pin TSSOP and 24-pin VQFN packages.
