The ADRF6518ACPZ-WP is a high-performance, dual-channel integrated circuit combining programmable filters and variable gain amplifiers (VGA). It features 63 MHz 6-pole Butterworth filters with 1 MHz step resolution, 72 dB continuous gain control, and 30 dB digital gain control, enabling precise signal conditioning for high-bandwidth applications. The device supports differential input/output with low noise and distortion, making it ideal for IQ communication systems, ADC drivers, and point-to-point radios. Operating from a 3.3 V single supply with SPI-programmable gain and filter settings, it is optimized for space-constrained and power-sensitive designs.
Key Features:
- Dual-Channel Architecture: Two matched channels with independent gain and filter control.
- Programmable Filters: 6-pole Butterworth filters (1 MHz–63 MHz, 1 MHz steps) with bypass mode for high-frequency operation.
- Wide Gain Range: Continuous gain control up to 72 dB and digital gain steps of 30 dB.
- Low Noise & Distortion: HD2/HD3 > 65 dBc, IMD3 > 65 dBc at 1.5 V p-p output.
- Flexible Power Options: 3.3 V supply with shutdown mode (<10 mA power consumption).
- Compact Packaging: 32-lead LFCSP package with exposed pad for thermal management.
Applications:
- Baseband IQ Receivers: Suppresses out-of-band interference while preserving signal integrity.
- ADC Drivers: Reduces ADC bandwidth requirements in high-speed systems.
- Point-to-Point Radios: Supports multi-carrier signals with low adjacent channel leakage.
- Instrumentation & Medical: Provides precise signal amplification for sensors and diagnostic equipment.
