It accepts a true bipolar differential input signal, meaning it can digitize both positive and negative voltages referenced to a common-mode point without external level-shifting circuitry. The single-ended-to-differential conversion is handled internally by the S/H-ADC front end (1:1 ratio), simplifying the analog interface for precision measurement chains. The digital side offers three interface options — SPI, parallel, and DSP — making it adaptable to a wide range of host controllers and FPGA-based systems. A single external reference sets the full-scale range, giving the designer control over the LSB weight and input span. ## Lifecycle and supply position The AD7665ASTZRL carries an active lifecycle status — no last-time-buy notice, no NRND flag. For a BOM line that needs a 16-bit SAR ADC with true bipolar input, this part is a safe long-term selection without obsolescence risk.","metaTitle":"AD7665ASTZRL 16-bit SAR ADC, 570k SPS, 48-LQFP","metaDescription":"ADI AD7665ASTZRL PulSAR® 16-bit SAR ADC, 570k samples/sec, differential input, true bipolar, SPI/Parallel/DSP interface, 48-LQFP.","metaKeywords":null},"attributes":{"series":"PulSAR®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"PulSAR®","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"True Bipolar","Input Type":"Differential","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI, Parallel, DSP","Number of Bits":"16","Package / Case":"48-LQFP","Reference Type":"External","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-LQFP (7x7)","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"570k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$44.38","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$44.38000","currency":"USD"},{"qty":10,"price":"$41.40800","currency":"USD"},{"qty":25,"price":"$39.67280","currency":"USD"},{"qty":100,"price":"$35.95350","currency":"USD"},{"qty":250,"price":"$34.71368","currency":"USD"},{"qty":2000,"price":"$30.74642","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/AD7665.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does AD7665ASTZRL require an external reference?","answer":"Yes, the AD7665ASTZRL uses an external reference.
