Replacement verdict
Compatible functional replacement candidate
The AD5541CRZ and AD5541CR are functionally equivalent 16-bit serial-input voltage-output DACs from Analog Devices, with the CRZ grade offering a lead-free, RoHS-compliant package variant of the same die and specification. Both parts share identical resolution, interface, reference architecture, and operating temperature range, making the AD5541CRZ a suitable drop-in replacement for the AD5541CR in most designs, provided the lead-free package and RoHS compliance are acceptable for the target application.

Frequently asked questions
What is the difference between the AD5541CRZ and the AD5541CR?
The AD5541CRZ and AD5541CR are both 16-bit, single-channel, serial-input voltage-output DACs from Analog Devices. The primary difference is the package and ordering option: the AD5541CR is specified in the SOIC-8 package, while the AD5541CRZ is the RoHS-compliant version of the same device in the SOIC-8 package. The "Z" suffix indicates RoHS compliance. Both are specified over the commercial temperature range of 0°C to +70°C.
Are the AD5541CRZ and AD5541CR functionally interchangeable?
Yes. The AD5541CRZ and AD5541CR are functionally identical. The AD5541CRZ is the RoHS-compliant equivalent of the AD5541CR. Both have the same 16-bit resolution, serial interface, output voltage range, and specified performance. The only difference is the RoHS compliance status indicated by the "Z" suffix.
What is the resolution and architecture of the AD5541CRZ and AD5541CR?
Both devices are 16-bit, single-channel, voltage-output digital-to-analog converters. They use a segmented R-2R ladder architecture and provide a unbuffered voltage output. The devices operate from a single 2.7 V to 5.5 V supply and include an internal reference buffer.
What is the serial interface used by the AD5541CRZ and AD5541CR?
Both devices use a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards. The interface consists of a serial clock (SCLK), a serial data input (DIN), and a chip select (SYNC) input. Data is clocked into a 16-bit shift register on the falling edge of SCLK.
What is the supply voltage range for the AD5541CRZ and AD5541CR?
Both the AD5541CRZ and AD5541CR operate from a single supply voltage ranging from 2.7 V to 5.5 V. The devices also require a reference voltage input (VREF) that sets the full-scale output voltage.
What is the output voltage range of the AD5541CRZ and AD5541CR?
The output voltage range is determined by the external reference voltage applied to the VREF pin. The output swings from 0 V to VREF. The devices provide a unbuffered output, so the output impedance is code-dependent and the output should be buffered for most applications.
What package options are available for the AD5541CRZ and AD5541CR?
Both the AD5541CRZ and AD5541CR are available in an 8-lead SOIC package. The AD5541CRZ is the RoHS-compliant version, while the AD5541CR is the non-RoHS version. The package dimensions and pinout are identical.
What is the operating temperature range for the AD5541CRZ and AD5541CR?
Both the AD5541CRZ and AD5541CR are specified for the commercial temperature range of 0°C to +70°C. For industrial temperature range versions, refer to other grade options such as the AD5541BRZ or AD5541ARZ.
Can the AD5541CRZ be used as a direct drop-in replacement for the AD5541CR?
Yes. The AD5541CRZ is a direct drop-in replacement for the AD5541CR. They share the same package, pinout, electrical specifications, and functional behavior. The only difference is that the AD5541CRZ is RoHS-compliant, which may be required for certain applications and markets.
