AD9650USVZ-105EP

Analog To Digital Converters (ADC) Overview

The AD9650USVZ-105EP is a dual 16-bit, 105 MSPS analog-to-digital converter (ADC) designed for high-frequency signal digitization up to 300 MHz. It features a multistage differential pipelined architecture with integrated output error correction and a shared voltage reference. The device operates on a single 1.8 V supply with separate digital driver supplies supporting 1.8 V CMOS or LVDS outputs. Key specifications include an SNR of 80.5 dBFS at 30 MHz input, SFDR of 93 dBc, and power consumption of 328 mW per channel at maximum speed. It is housed in an 80-lead TQFP package with an exposed pad, rated for extended temperatures from −55°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix USVZ indicates the 80-lead TQFP package variant when sourcing this component. Confirm RoHS compliance status as indicated by the Z suffix in official Analog Devices documentation. Ensure the procurement channel provides valid traceability for the EP (Enhanced Product) designation required for extended temperature reliability. Cross-reference the latest datasheet revision to confirm pinout compatibility with existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 16-bit precision is required at sampling rates up to 105 MSPS. The LVDS output option minimizes noise in high-speed digital interfaces. Consider the 500 MHz analog input bandwidth for wide dynamic range applications. The integrated reference simplifies board layout compared to external reference solutions. Evaluate thermal performance given the 80-lead TQFP package constraints in enclosed environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9650-EP family, which represents the enhanced product version of the standard AD9650 series. While the standard AD9650 uses a 64-lead LFCSP package, the USVZ suffix denotes the 80-lead TQFP configuration. The EP designation signifies qualification for extended industrial temperature ranges and potentially stricter manufacturing controls compared to commercial grade parts.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the unique 80-lead TQFP form factor. Standard AD9650 variants use a 64-lead LFCSP and require PCB redesign. No other Analog Devices dual 16-bit ADCs share this exact package and specification combination.
