DAC81404RHBT Description

The DAC81404RHBT from Texas Instruments is a high-performance, 16-bit, quad-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Packaged in a compact 32-VQFN surface-mount form factor, this device integrates four independent DACs with ±1LSB INL/DNL (integral/differential nonlinearity) for exceptional accuracy. It supports a wide analog supply voltage range (4.5V to 41.5V) and a digital supply range (4.5V to 5.5V), making it versatile for industrial and automation systems. Featuring a serial SPI interface, it ensures seamless communication with microcontrollers or FPGAs. The internal reference and differential output further enhance signal integrity, while a 1.2ms settling time enables rapid response in dynamic applications.
