Data Acquisition - Analog to Digital Converters (ADC) convert analog electrical signals into digital signals for subsequent processing. The ADS7812UBG4 is a 12 bit 8 channel sample and hold, parallel analog to digital converter with auto scan and sample/hold amplifier. It is designed to interface directly with 8-bit or 16-bit microprocessors.

The ADS7812UBG4 offers 8-bit resolution, automatic input scanning, an internal sample and hold capacitor, an output latch and sample and hold capacitor, and an internal clock generator. The input clock can be up to a maximum of 4 MHz. It also features a multiplexing feature which allows the input signals to be connected to the corresponding output channels. This allows for multiple channels of data acquisition in a single cycle.

The ADS7812UBG4 operates with a single +5V supply. The minimum operating voltage is 3.3V and the maximum is +6V. The power supply rejection ratio (PSRR) is adiabatic and is rated at 70dB. This allows for a low noise floor from the power supply.

The digital interface of the ADS7812UBG4 is compatible with many 8-bit and 16-bit microprocessors. The input scanning is software or hardware driven. The pins used for the external clock, valid clock and select enable can be used in a multiplexing mode, allowing multiple channel collection with a single scan. The high input impedance of the amplifier allows for direct connection of transducers without additional circuit complexity.

The internal references are factory trimmed and are stable over supply voltage and temperature variations. The analog input range can be 1V, 1.5V, 2V and 4V ranges, with additional ranges available on special order. The output code is linear over the full input range, providing excellent accuracy and resolution.

The ADS7812UBG4 features an auto scan feature, which allows the conversion of multiple channels in one sequence. The scan cycle is divided into 16 conversion cycles, 8 of which are used for the analog-to-digital conversion, and 8 for the digital-to-digital conversions. This feature provides for faster data acquisition, allowing for multiple channels to be acquired quickly.

The ADS7812UBG4 also features low power consumption, allowing for lower cost and more efficient applications. The power dissipation of the unit is less than 5mA, which is a fraction of the power consumed by other ADC solutions. The low power consumption makes the unit ideal for battery operated applications, where power efficiency is essential.

The ADS7812UBG4 is a versatile analog to digital converter which offers a wide range of features and capabilities. The unit is well suited for many data acquisition applications, providing excellent accuracy, resolution and speed. With its low power dissipation, it can be used in a variety of portable and low cost applications, making it an attractive option for many applications.
