Analog Devices Inc. ADA4932-2YCPZ-RL

Overview

ADA4932-2YCPZ-RL from Analog Devices is a dual-channel, low-power, high-speed differential amplifier optimized as an ADC driver for precision data acquisition systems. It delivers −3 dB small-signal bandwidth of 560 MHz (±5 V), 0.1% settling time of 9 ns, 2800 V/µs slew rate, and 100 dB SFDR at 10 MHz - enabling high-fidelity signal conditioning in IF/baseband stages of communications and instrumentation receivers.

For engineers reviewing the ADA4932-2YCPZ-RL datasheet, ADA4932-2YCPZ-RL pinout, ADA4932-2YCPZ-RL application, or ADA4932-2YCPZ-RL equivalent, this page provides verified specifications, validated dual-amplifier pin mapping, real-world ADC interface use cases, and two confirmed alternative drivers with documented functional trade-offs.

Technical Context

The ADA4932-2YCPZ-RL implements a dual independent voltage-feedback architecture with separate VOCM inputs per channel and fully decoupled differential feedback paths (RF/RG). Each amplifier features internal common-mode feedback that forces output common-mode voltage to match the VOCM input while maintaining >60 dB output balance error up to 1 MHz.

It operates from ±5 V or single +5 V supply, supports externally adjustable gain ≥0.5 (including attenuating configurations), and accepts input common-mode voltages from −VS + 0.2 V to +VS − 1.8 V - enabled by input stage biasing shifted down by 1 V_BE. The SiGe process ensures 3.6 nV/√Hz input voltage noise and <±0.5 mV typical input offset voltage across −40°C to +105°C.

Key Specifications

Pinout & Package

ADA4932-2YCPZ-RL is housed in a 24-lead, 4 mm × 4 mm, 0.8 mm height LFCSP package with exposed paddle (EPAD) for thermal and electrical grounding. Pinout is optimized for symmetric PCB layout to minimize parasitic imbalance between channels.

FAQ

What is the maximum operating temperature range for the ADA4932-2YCPZ-RL?

The ADA4932-2YCPZ-RL is specified to operate over the industrial temperature range of −40°C to +105°C. This rating is validated across all key parameters including bandwidth, SFDR, and output balance error - ensuring reliable performance in base station radios, motor control enclosures, and portable diagnostic equipment where ambient temperatures exceed 85°C.

Can the ADA4932-2YCPZ-RL drive a 100 Ω differential load while maintaining 0.1 dB gain flatness?

Yes - the ADA4932-2YCPZ-RL maintains 0.1 dB gain flatness to 100 MHz into a 200 Ω differential load (RL,dm = 200 Ω) under ±5 V operation. For 100 Ω loads, gain flatness degrades slightly but remains within 0.25 dB to 80 MHz; design margin is preserved by using recommended 53.6 Ω series termination (RT) per output leg as specified in Figure 51 of the datasheet for ADA4932-2YCPZ-RL.

Does the ADA4932-2YCPZ-RL support single-ended input with DC coupling?

Yes - the ADA4932-2YCPZ-RL supports single-ended-to-differential conversion with DC coupling using a standard four-resistor network (RF/RG per side) and proper input biasing. Its input common-mode range extends from −VS + 0.2 V to +VS − 1.8 V, allowing direct connection to grounded or negatively biased sources without AC coupling capacitors - a capability confirmed in Table 1 and Figure 54 of the ADA4932-2YCPZ-RL datasheet.

How does the power-down feature work on the ADA4932-2YCPZ-RL?

The ADA4932-2YCPZ-RL has two independent power-down pins (PD1 and PD2), one per amplifier. Driving PDx to ≤(+VS − 2.8) V disables the corresponding channel, reducing quiescent current to 0.8 mA. Turn-on occurs within 16 ns when PDx rises to ≥(+VS − 2.2) V. This enables precise channel gating in time-interleaved ADC systems or burst-mode receivers without affecting the active channel's performance.

Is the ADA4932-2YCPZ-RL pin-compatible with the ADA4932-1YCPZ-R7?

No - the ADA4932-2YCPZ-RL (24-lead LFCSP) is not pin-compatible with the ADA4932-1YCPZ-R7 (16-lead LFCSP). They differ in pin count, pin assignment, and internal routing: ADA4932-2YCPZ-RL provides separate VOCM, PD, and supply pins for each channel, while ADA4932-1YCPZ-R7 shares these functions across a single amplifier. PCB layout and schematic must be redesigned when substituting ADA4932-2YCPZ-RL for ADA4932-1YCPZ-R7.
