Each input accepts either differential or pseudo-differential signals, giving the designer flexibility to handle a true differential sensor pair or a single-ended signal referenced to a common return without an external op-amp stage. ## Supply rails and interface The analog and digital supply ranges overlap at 3.13 V to 3.47 V, and the part also accepts a separate 5 V analog rail — this lets the ADC run from a common 3.3 V bus while keeping the analog front-end on a cleaner 5 V supply for better SNR on the input signal. Data is read out via either an LVDS serial interface (for high-speed, low-noise transfer over longer traces) or a standard CMOS serial interface — the dual-mode output lets the same part serve a backplane with LVDS receivers or a local SPI port.","metaTitle":"LTC2321IUFD-14#PBF 14-bit SAR ADC, 2 MSPS, 28-QFN","metaDescription":"LTC2321IUFD-14#PBF 14-bit SAR ADC, 2 MSPS, dual differential/pseudo-differential inputs, LVDS/Serial interface, -40°C to 85°C, 28-QFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Features":"Simultaneous Sampling","Input Type":"Differential, Pseudo-Differential","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"LVDS - Serial, Serial","Number of Bits":"14","Package / Case":"28-WFQFN Exposed Pad","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-QFN (4x5)","Number of A/D Converters":"2","Voltage - Supply, Analog":"3.13V ~ 3.47V, 5V","Voltage - Supply, Digital":"3.13V ~ 3.47V, 5V","Sampling Rate (Per Second)":"2M"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.66","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$20.66000","currency":"USD"},{"qty":10,"price":"$19.05700","currency":"USD"},{"qty":25,"price":"$18.20000","currency":"USD"},{"qty":100,"price":"$16.27310","currency":"USD"},{"qty":250,"price":"$15.52368","currency":"USD"},{"qty":500,"price":"$14.77428","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6be023a492db0fd4a90e7126b5b97dff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does LTC2321IUFD-14#PBF compare to AD7902BRQZ-RL7?","answer":"The AD7902BRQZ-RL7 is a 16-bit, 1 MSPS PulSAR ADC with a pseudo-differential input and an SPI/DSP serial interface — it trades half the sample rate and a different interface for two more bits of resolution.
