Analog Devices Inc. AD8352ACPZ-R7

Overview

AD8352ACPZ-R7 from Analog Devices is a 2.2 GHz ultralow-distortion differential RF/IF amplifier optimized for driving high-speed ADCs and interfacing SAW filters. It delivers 10 dB gain (AV = 10 dB), −84 dBc HD3 at 100 MHz, 40 dBm OIP3, 2.7 nV/√Hz input-referred noise, and operates from 3 V to 5.5 V supply. Its constant 3 kΩ input resistance simplifies impedance matching in RF receiver front-ends.

For engineers reviewing the AD8352ACPZ-R7 datasheet, AD8352ACPZ-R7 pinout, AD8352ACPZ-R7 application, or AD8352ACPZ-R7 equivalent, key selection criteria include differential output drive capability, single-resistor gain adjust (3–25 dB), distortion optimization via RD/CD network, fast settling (<2 ns), and LFCSP-16 package compatibility with high-frequency layout requirements.

Technical Context

The AD8352ACPZ-R7 employs a SiGe XFCB3 process to achieve broadband linearity up to 2.2 GHz (−3 dB BW at AV = 10 dB) while maintaining low noise (2.7 nV/√Hz RTI) and high slew rate (8 V/ns). Its buffered gain-setting architecture isolates RG from signal paths, preserving stable 3 kΩ input impedance across all gain settings.

It supports both differential and single-ended input configurations, with dedicated pins for common-mode voltage control (VCM), enable (ENB), and distortion tuning (RDP/RDN). Output features 100 Ω nominal differential impedance and ±10 mV output offset, enabling direct interface to 100 Ω differential ADC inputs without external termination.

Key Specifications

Pinout & Package

The AD8352ACPZ-R7 is housed in a 3 mm × 3 mm, 16-lead LFCSP package with exposed thermal pad requiring low-impedance ground connection. Pin 1 (RDP) to Pin 16 (VIP) follow standard top-view numbering; EPAD must be soldered to GND for thermal and electrical stability.

FAQ

What is the maximum operating frequency of the AD8352ACPZ-R7?

The AD8352ACPZ-R7 achieves a −3 dB bandwidth of 2.2 GHz at AV = 10 dB, with usable gain flatness up to 300 MHz (0.2 dB) and functional operation beyond 500 MHz. Its SFDR exceeds 65 dB up to 500 MHz, confirming reliable RF/IF amplification through the L-band.

How do I configure the AD8352ACPZ-R7 for single-ended input operation?

To configure the AD8352ACPZ-R7 for single-ended input, drive VIP while connecting a 200 Ω resistor (RN) between VIP and RGN. Use RG values from Table 7 (e.g., 120 Ω for 12 dB gain into 200 Ω load) and retain RD/CD components for distortion optimization. The AD8352ACPZ-R7 maintains <2 ns settling and −83 dBc HD3 performance in this mode.

Does the AD8352ACPZ-R7 require external baluns for differential output?

No - the AD8352ACPZ-R7 provides true differential outputs (VOP/VON) with 100 Ω nominal impedance and inherent common-mode rejection. Baluns are optional and only used in legacy designs requiring single-ended output conversion; modern ADC interfaces use direct differential connection to maximize SNR and minimize component count.

What is the purpose of the RDP and RDN pins on the AD8352ACPZ-R7?

RDP and RDN on the AD8352ACPZ-R7 are dedicated distortion-adjust terminals. Connecting an RD resistor and CD capacitor between them forms a feedforward cancellation network that reduces second- and third-harmonic distortion - especially effective at frequencies below 300 MHz. For example, RD = 4.3 kΩ and CD = 0.2 pF optimize HD3 at 100 MHz.

Can the AD8352ACPZ-R7 drive a 50 Ω single-ended load?

The AD8352ACPZ-R7 is designed for 100 Ω differential loads (e.g., 200 Ω across VOP–VON). Driving a 50 Ω single-ended load requires external impedance transformation (e.g., 1:2 balun or resistive pad), which degrades noise figure and OIP3. For optimal performance, match to its native 100 Ω differential output impedance using standard ADC evaluation boards or PCB layout practices.
