The AD5315BRMZ is a precision, low power, 9-bit Digital-to-Analog Converter (DAC) that operates off a single 2.7 V to 5.5 V supply. The device has outstanding ac performance with 1 MHz bandwidth and THD of 0.015%.

The AD5315BRMZ offers a selectable output range option of either 0 V to 2.5 V or 0 V to 5 V. The AD5315BRMZ also offers a versatile set of features including two-wire compatible serial data interface, automatic power-down management, bipolar reference input range from 0 V to 5 V, and excellent temperature characteristics.

The AD5315BRMZ features a high-resolution 9-bit voltage output over a specified ±2.0 LSB error of linearity, an SOIC-16 package, a convenient 2-wire serial interface, and a wide range of power supply rejection over its full operating temperature range. It provides automatic power shutdown and consumes only 600 μA of supply current when disabled. The AD5315BRMZ also provides a differential, adjustable reference input of 0 V to 5 V and is ideal for dividing a wide reference range such as 5 V or ±5 V.

The AD5315BRMZ is especially suited for applications such as motor control, data acquisition, instrumentation, and audio and video systems. The device is suitable for both single-ended and differential input applications. It is also ideal for dB scaling applications, where the reference is used as the dB reference to achieve accurate dB scaling.

The AD5315BRMZ also offers various features such as data replays, quick response rates and low power dissipation. It features a fast settling time (4 μs) and a 13 MHz 3-wire serial interface with a 0 to 5 V bipolar reference input.

The AD5315BRMZ has an AUTO power-down management feature that reduces the current consumption to less than 0.1 μA. The device also includes a user-programmable shutdown feature that allows users to program the device to enter a standby mode upon receiving a high logic level on the CS/SDI pin. When in the shutdown mode, the DAC output is clamped to a 0 V level.

The working principle of the AD5315BRMZ is quite simple. It converts a digital input signal into a corresponding analog output voltage. The input word length is 9-bit and the output voltage range can be 0 V to 2.5 V or 0 V to 5 V depending on the integrated range selection pin. The device takes a digital input from the 3-wire serial interface and provides a corresponding analog voltage output.

The device features high accuracy with a specified error of linearity of ±2.0 LSB, an input data update rate of u14 MHz, and a fast settling time (4 μs). It also features a user-programmable power-down feature which enables it to enter a low power standby mode upon receiving a high logic level on the CS/SDI pin.

In conclusion, the AD5315BRMZ is a high-precision, low power, 9-bit Digital-to-Analog Converter (DAC) which is suitable for applications such as motor control, data acquisition, instrumentation, and audio and video systems. The device features an SOIC-16 package, a convenient 3-wire serial interface, and a wide range of power supply rejection over its full operating temperature range. It features a low operating current (0.6 mA) and a wide output swing range (0 V to 2.5 V or 0 V to 5 V).
