Frequently Asked Questions
What type of op-amp is the AD8051ARTZ-R2 and what is its output swing?
The AD8051ARTZ-R2 is a single voltage-feedback operational amplifier with rail-to-rail output capability. Rail-to-rail output means the output voltage can swing very close to both the positive and negative supply rails, which maximizes the usable signal range in low-voltage single-supply designs operating on 6 V to 12 V.
What is the CMRR specification for the AD8051ARTZ-R2?
The AD8051ARTZ-R2 has a minimum common-mode rejection ratio (CMRR) of 72 dB and a typical CMRR of 88 dB. CMRR measures how well the amplifier rejects signals that appear equally on both input terminals, which is important in sensor applications where the signal of interest rides on a common-mode offset or interference voltage.
What package does the AD8051ARTZ-R2 come in?
The AD8051ARTZ-R2 comes in a 5-pin SOT-23 surface-mount package (manufacturer code RJ-5). This very small package is ideal for space-constrained PCB designs in portable devices. The R2 suffix indicates it is supplied in tape-and-reel format optimized for automated pick-and-place assembly.
What are common applications for the AD8051ARTZ-R2?
Common applications include ADC input buffers, active low-pass and band-pass filters, sensor signal conditioning amplifiers, and transimpedance amplifiers for photodiode circuits. Its rail-to-rail output and high CMRR are particularly valuable in precision measurement systems, portable medical devices, and industrial sensor interfaces operating from single or split low-voltage supplies.
