ADI AD5398BCPZ Single 10-Bit DAC With 120 mA Output Currentsink Capability

Shenzhen Mingjiada Electronics Co., Ltd. is a professional electronic component supplier, long-term supply of AD5398BCPZ, a single-channel 10-bit analog converter (DAC) with 120mA output current absorption capacity. 

Product Description Of AD5398BCPZ

AD5398BCPZ is a single 10-bit DAC with 120 mA output current sink capability. It features an internal reference and operates from a single 2.7 V to 5.5 V supply. The AD5398BCPZ DAC is controlled via a 2-wire (I2C-compatible) serial interface that operates at clock rates up to 400 kHz.

AD5398BCPZ incorporates a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write takes place. It has a power-down feature that reduces the current consumption of the device to 1 µA maximum. The AD5398BCPZ is designed for autofocus, image stabilization, and optical zoom applications in camera phones, digital still cameras, and camcorders.

AD5398BCPZ also has many industrial applications, such as controlling temperature, light, and movement, over the range −40°C to +85°C without derating.

The I2C address range for the AD5398BCPZ is 0x18 to 0x1F inclusive.
