The AD5553CRMZ is a high precision, low power, complete 12-bit monolithic digital-to-analog converter (DAC) that can be used in a wide variety of applications. It features an 8-pin TSSOP package, extended temperature range and an integrated reference current source. The DAC is buffered by an internal unity gain voltage op amp which can be enabled or disabled independently of the DAC.

The AD5553CRMZ can be used in both industrial and consumer applications, such as electrical motor control, data acquisition, communication systems, motion control, automotive, consumer electronics and instrumentation systems. It is designed to interface directly with logic and memory circuits, providing 12-bit resolution conversion. The output stage is capable of driving up to +17 dBm. It is available in a compact 8-pin TSSOP package, offering extended temperature range (-40°C to +85°C) operation.

The AD5553CRMZ provides a high level of monotonicity, excellent linearity and low noise performance. The maximum sampling rate is16MHz and the output transition time is 0.7μs. This device consumes only 500μA of max current from the reference pin and the logic pins consume 2mA of max current at 5V. It also has dual stage low-pass filters for high performance and optimal noise prevention.

The AD5553CRMZ implements a single supply operation, with a voltage range of 4.75 to 5.25V, and an external reference current source. When enabled, it automatically routes the reference current into the buffer amplifier. The output range is 0 to Vref and the gain is adjustable via the external reference pin. The device also allow a user to connect a digital trimming register for self-calibration. The trimming procedure is optimized for reduced dynamic errors and improved accuracy.

In summary, the AD5553CRMZ is a high precision, low power, 12-bit monolithic DAC with extended temperature range. It is ideal for various data acquisition, communication and instrumentation applications, providing 12-bit resolution conversion. The device is buffered by an internal unity gain voltage op-amp and it offers dual stage low-pass filters for high performance. It also offers a digital trimming register for self-calibration and its operating temperature range is -40°C to +85°C.
