This is a 16-bit, dual-channel SAR ADC sampling at 25 MSPS. Two independent converters on one die deliver matched timing without the skew of separate ADCs. The single-ended input configuration simplifies the front-end drive: no differential amplifier needed if the source is ground-referenced. The 0:2 S/H-to-ADC ratio means each channel has its own sample-and-hold, so both inputs are sampled simultaneously — no interleaving skew. ## Reference and interface flexibility The ADC3662IRSBT supports both internal and external reference. Using the internal reference saves a component and board area; swapping to an external precision reference (e.g., a low-drift bandgap) improves gain accuracy and temperature drift for metrology-grade measurements. The LVDS serial data interface keeps the digital bus clean at 25 MSPS — no parallel bus noise coupling into the analog supply. SPI is available for configuration and status readback. Supply rails are 1.75 V to 1.85 V for both analog and digital domains, which means a single 1.8 V rail can power the entire ADC. The narrow range demands a clean regulator — a 1.8 V LDO with <10 µVrms noise is typical for the analog supply. ## Package and temperature grade — design-in checklist The exposed-pad package with a 5x5 mm body requires a thermal pad on the PCB for heat sinking.","metaTitle":"ADC3662IRSBT 16-bit 25-MSPS dual SAR ADC - TI ADC366x","metaDescription":"Texas Instruments ADC3662IRSBT dual-channel 16-bit SAR ADC, 25 MSPS, LVDS/SPI, internal reference, -40 to 105°C.
