Overview
The AD5340BRUZ-REEL7 is a single 12-bit Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device operates from a supply voltage range of 2.5 V to 5.5 V and consumes a low current of 115 μA at 3 V. It features a parallel interface and includes an on-chip output buffer that can drive the output to both supply rails, enabling rail-to-rail operation. The AD5340BRUZ-REEL7 is available in a 24-lead Thin Shrink Small Outline Package (TSSOP) and is RoHS compliant.

Key Features
- Parallel Interface: The device uses a parallel interface with CS and WR pins to load data into the input registers.
- Buffered or Unbuffered Reference Input: The AD5340 allows a choice between buffered or unbuffered reference input.
- Gain Control: The GAIN pin allows setting the output range to either 0 V to VREF or 0 V to 2 × VREF.
- Double-Buffered Input Data: Enables simultaneous update of multiple DACs using the LDAC pin.
- Asynchronous CLR Input: Resets the contents of the input register and the DAC register to all zeros.
- Power-On Reset Circuit: Ensures the DAC output powers on to 0 V and remains there until valid data is written.
- Low Power Consumption: Consumes only 115 μA at 3 V and reduces to 80 nA in power-down mode.
- Rail-to-Rail Operation: The on-chip output buffer drives the output to both supply rails.
