Analog Devices Inc. ADA4930-2YCPZ-RL

Overview

ADA4930-2YCPZ-RL from Analog Devices is a dual-channel, ultralow-noise (1.2 nV/√Hz), high-speed differential amplifier optimized as an ADC driver for 14-bit, 1.8 V supply ADCs up to 70 MHz. It supports single-ended-to-differential and differential-to-differential conversion with externally adjustable gain, 3.3 V or 5 V single-supply operation, and independent power-down control per channel.

For engineers reviewing the ADA4930-2YCPZ-RL datasheet, ADA4930-2YCPZ-RL pinout, ADA4930-2YCPZ-RL application, or ADA4930-2YCPZ-RL equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in RF/IF signal chains, and confirmed alternative options for ADC interface design.

Technical Context

The ADA4930-2YCPZ-RL implements a dual, fully differential architecture with two independent internal common-mode feedback loops-one per channel-enabling precise VOCM tracking (±15 mV offset at 5 V) and exceptional output balance (>55 dB up to 1 MHz). Each channel features matched input resistance (150 kΩ diff, 3 MΩ cm), low input bias current (−34 to −15 μA), and rail-to-rail output swing capability under load.

Its SiGe complementary bipolar process delivers simultaneous high bandwidth (1.35 GHz small-signal BW at G = 1), fast slew rate (3400 V/μs), and ultra-low harmonic distortion (−104 dBc HD2 at 10 MHz, −82 dBc HD3 at 70 MHz), making it suitable for wideband IF sampling and high-fidelity data acquisition where noise, linearity, and settling time are critical.

FAQ

What is the maximum operating frequency supported by the ADA4930-2YCPZ-RL?

The ADA4930-2YCPZ-RL achieves a −3 dB small-signal bandwidth of 1.35 GHz at G = 1 with 5 V supply, and maintains 0.1 dB gain flatness to 90 MHz (dual-channel mode). Its usable small-signal range extends reliably to 380 MHz for the ADA4930-1 variant, but the ADA4930-2YCPZ-RL is characterized to 90 MHz for flatness due to inter-channel coupling effects-verified in Table 1 and Figure 17 of the Rev. B datasheet.

Does the ADA4930-2YCPZ-RL support single-ended input configurations?

Yes, the ADA4930-2YCPZ-RL supports single-ended-to-differential conversion using standard resistor feedback networks. Per Figure 42 and "Theory of Operation" section, connecting VIN to +IN1 (Pin 24) while grounding −IN1 (Pin 7) configures Channel 1 for SE input; identical routing applies to Channel 2. The internal common-mode feedback loop automatically balances outputs regardless of input configuration.

What is the purpose of the VOCM pins on the ADA4930-2YCPZ-RL?

The VOCM1 (Pin 17) and VOCM2 (Pin 11) pins set the output common-mode voltage for each differential pair independently. Applying a dc voltage (0.5–2.3 V at 5 V supply) forces +OUT/−OUT voltages to center around that level-enabling precise matching to ADC input common-mode requirements (e.g., 0.9 V for 1.8 V-core ADCs). This is implemented via internal feedback, not passive resistive division.

Can both channels of the ADA4930-2YCPZ-RL be powered down independently?

Yes, the ADA4930-2YCPZ-RL provides dedicated PD1 (Pin 20) and PD2 (Pin 14) control lines. Driving PD1 < 2.5 V disables Channel 1 (quiescent current drops to ≤2.6 mA), while PD2 < 2.5 V disables Channel 2-each with 12 ns turn-on and 1 μs turn-off times. This enables true per-channel power gating in multi-path or TDD systems without affecting the active channel's performance.

What package type and thermal characteristics does the ADA4930-2YCPZ-RL have?

The ADA4930-2YCPZ-RL uses a 4 mm × 4 mm, 24-lead LFCSP package with exposed thermal paddle (EPAD), specified with θJA = 67°C/W on a JEDEC 4-layer board. The EPAD must be soldered to a thermally conductive ground or power plane-per Figure 5 notes-to maintain junction temperature ≤150°C at full load. Absolute max supply is 5.5 V; storage range is −65°C to +125°C.
