ADL5561ACPZ-R7 2.9 GHz Differential Amplifier / ADC Driver
The ADL5561ACPZ-R7 is a high-performance differential amplifier designed for RF / IF signal conditioning and high-speed ADC driving in demanding applications. With ultra-low noise (2.1 nV/√Hz) and exceptionally low distortion (HD2 < -90 dBc), this IC ensures precise signal amplification for 5G base stations, radar systems, medical imaging, and test equipment.
Featuring flexible gain configuration (6 dB / 12 dB / 15.5 dB), the LFCSP-16 packaged amplifier operates across industrial temperature range (-40°C to +85°C). Broadband performance (2.9 GHz bandwidth) and single-supply operation (2.8V-3.6V) simplify integration into space-constrained PCB designs.
Typical Applications
- High-speed ADC driver — interfacing analog signals to 12-16 bit ADCs.
- 5G base station IF amplifier — intermediate frequency signal conditioning.
- Radar receivers — low-noise pre-amplification.
- Medical imaging — ultrasound / CT analog front-end.
- Spectrum analyzers — test equipment signal conditioning.

FAQ — ADL5561 Differential Amplifier
Q: Differential vs single-ended amp?
A: Differential amps drive high-speed ADCs with better common-mode rejection and dynamic range. Modern 12-16 bit ADCs prefer differential inputs.
Q: SiGe process advantage?
A: Silicon-Germanium offers better high-frequency performance vs pure silicon. Required for GHz-class amplifier work.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
