7. Functional Description

• Dual independent differential amplifiers
• Fixed gain of 16 dB (diff) / 14 dB (SE)
• Gain adjustable 0–16 dB using external series resistors
• VCOMx sets output common‑mode voltage (defaults to VCC/2 if open)
• ENBLx enables/disables each channel independently
• Internal resistors set fixed gain; external resistors reduce gain
• Optimized for high‑speed ADC driving, differential conversion, and IF/RF gain blocks

8. Application Information

Typical Applications

• High‑speed differential ADC drivers
• Single‑ended to differential conversion
• IF / RF gain blocks
• SAW filter and analog front‑end interfaces
• Zero‑IF / complex‑IF receivers
• Test & measurement equipment

Basic Application Requirements

• Decouple VCC1/VCC2 with 0.1 µF + 10 µF capacitors
• Decouple VCOM1/VCOM2 with 0.1 µF capacitors
• Drive ENBL high to enable; low to power down
• Use 200 Ω differential load for rated distortion performance
• Input/output can be AC‑ or DC‑coupled

Gain Adjustment

• Place series resistors at inputs to reduce gain from 16 dB down to 0 dB
• Equations and lookup tables provided for desired gain vs. series resistance

9. Layout Guidelines

• Exposed pad must be soldered to low‑impedance ground plane
• Use multiple vias to connect pad to internal ground layers
• Keep input/output traces short; minimize parasitic capacitance
• Use ground planes to reduce noise and crosstalk
• Follow RF/high‑speed layout practices for wideband performance
