AD7533KRZ

AD7533 is a 10-bit multiplying digital-to-analog converter without internal output buffer amplifier. K denotes industrial temperature grade. RZ stands for 8-lead narrow SOIC surface mount package, supplied in tube packaging for prototype validation and small-batch production assembly.

This CMOS multiplying DAC features a segmented resistor ladder architecture, capable of four-quadrant multiplication with alternating current and direct current input signals. It operates on a single power supply ranging from 5 V to 15 V, and can also work with dual bipolar power rails for bipolar analog output generation.

The device has no built-in latch circuit, so digital input data must be held steadily during conversion. It supports parallel 10-bit binary digital input, with full-scale accuracy error tightly controlled to guarantee precise analog conversion results. Excellent linearity performance minimizes differential and integral non-linearity errors across the entire input range.

Multiplying function allows the reference input voltage to be dynamically varied from DC up to high frequency AC signals, which makes it suitable for programmable gain control and waveform generation circuits. Low power consumption is maintained under normal operating conditions, and the high input impedance of the resistor reference port imposes negligible load on the external voltage reference source. Minimal parasitic capacitance ensures stable performance for medium-frequency signal applications.

Encapsulated in compact 8-pin narrow SOIC plastic surface mount package with tiny footprint, saving PCB layout space for miniature analog control modules. Moisture Sensitivity Level is MSL3; all reflow soldering procedures must be completed within 168 hours once the original vacuum packaging is opened. Tube packaging supports manual breadboard debugging, performance testing and small-volume pre-production assembly conveniently.

The operating temperature range spans -40 °C to +85 °C, enabling continuous reliable operation in industrial process controllers, laboratory signal generators, portable calibration instruments and audio tuning equipment under fluctuating temperature environments. Manufactured with lead-free production processes, the component complies with global RoHS environmental directives. The simple peripheral circuit structure reduces the use of auxiliary passive components and simplifies programmable analog voltage and current output circuit design.
