The AD7306JR is a precision, low-power, dual, 12-bit buffered voltage-output A/D converter. It features excellent DC specifications, 12-bit monotonic performance, plus a low power dissipation of typically only 500 μW/channel. The digital portion of the converter consists of a separate serial interface, power-on reset, chip select and repeat flag logic, 12-bit DAC input latch, 12-bit data output latch, and status output latch. Its expansive application field and working principle explore below.

Application Field

The AD7306JR is a low-power, high-precision, digital-to-analog converter ideal for battery-powered systems, as well as portable and/ or remote systems. It is suitable for requirements such as pressure measurement, temperature measurement, vibration detection, position detection, and gas detection etc. The AD7306JR features an error-corrected voltage-output DAC with a bipolar output range of ± 10.24 V (on the Vref pin).

The AD7306JR also features a 15-lead micro-SMD package, 10-bit/8-bit data input format, ± 10V output range, and reference input range from +5V to +24V. It takes up only 1.6 x 2.6 mm space on the board, making it suitable for space-constrained applications. It operates on a single 3.0 to 3.6 V supply and provides power savings in portable equipment.

The product is offered in the extended temperature range (-40°C to +125°C). It is also available in a 5-lead UDFN package. This offers superior power performance solutions that are suitable across multiple applications.

Working Principle

The AD7306JR is a 12-bit voltage-output DAC that uses an 8-bit or 10-bit digital control word to control the current output of each channel. Up to eight different I-to-V conversion settings are available for each channel, and the current output is adjustable from 0 μA to ±20 μA for even greater flexibility. The AD7306JR is a low-power, high-precision, digital-to-analog conversion device. It features an error-corrected voltage-output DAC with a bipolar output range of ± 10.24 V (on the Vref pin). The AD7306JR features a 15-lead micro-SMD package, 10-bit/8-bit data input format, ± 10V output range, and reference input range from +5V to +24V.

The AD7306JR is a low-power device with a typical current dissipation of 500 μW/channel. It has excellent DC specifications including 8 LSBINL errors and 5 ppm/°C gain and offset drift. The digital portion of the converter consists of a separate serial interface, power-on reset, chip select and repeat flag logic, 12-bit DAC input latch, 12-bit data output latch, and status output latch. The AD7306JR is a high-precision, single-supply, buffered voltage-output DAC.

The AD7306JR is an ideal solution for precision applications such as pressure measurement, temperature measurement, vibration detection, position detection, and gas detection. It features a low power dissipation of typically only 500 μW/channel and its expansive application field makes it a suitable choice for battery-powered systems, as well as portable and/ or remote systems. The product is offered in the extended temperature range (-40°C to +125°C) and features an excellent monotonic performance of 12-bits.
