Analog Devices Inc. ADA4932-1YCPZ-R2

Overview

ADA4932-1YCPZ-R2 from Analog Devices is a low-power, high-speed differential amplifier optimized as an ADC driver for precision data acquisition systems. It delivers −3 dB bandwidth of 560 MHz (G = 1), 0.1 dB gain flatness to 300 MHz, 2800 V/µs slew rate, 9 ns 0.1% settling time, and 100 dB SFDR at 10 MHz - enabling high-fidelity signal conditioning in IF/baseband stages.

For engineers reviewing the ADA4932-1YCPZ-R2 datasheet, ADA4932-1YCPZ-R2 pinout, ADA4932-1YCPZ-R2 application, or ADA4932-1YCPZ-R2 equivalent, this page provides verified circuit role, package mapping, thermal performance, real-world distortion behavior at 20 MHz, and validated alternatives for single-ended-to-differential conversion in high-resolution ADC front-ends.

Technical Context

The ADA4932-1YCPZ-R2 implements dual feedback architecture: differential-mode gain set by external RF/RG resistor networks (e.g., 499 Ω/499 Ω for G = 1), and independent common-mode control via VOCM input with 0.998 V/V gain and 270 MHz small-signal bandwidth. Its SiGe complementary bipolar process enables 3.6 nV/√Hz input voltage noise and <±0.5 mV input offset while consuming only 9.6 mA per amplifier.

This architecture supports both single-ended-to-differential and differential-to-differential operation across ±5 V or +5 V/0 V supplies, with input common-mode range extended down by 1 V_BE and output balance error ≤−60 dB up to 1 MHz - critical for suppressing even-order harmonics in ADC sampling paths.

Key Specifications

Pinout & Package

ADA4932-1YCPZ-R2 is housed in a 16-lead 3 mm × 3 mm LFCSP package with exposed paddle (EPAD), offering 91°C/W junction-to-ambient thermal resistance on a 4-layer JEDEC board. The EPAD must be soldered to ground or power plane for optimal thermal and electrical performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential ADC driver applications.

Compared with ADA4940-1ACPZ-R7 and THS4561IRGET, the ADA4932-1YCPZ-R2 uniquely balances 560 MHz bandwidth, 9.6 mA quiescent current, and 3.6 nV/√Hz noise - making it optimal for 10–300 MHz high-SFDR data acquisition where thermal and power constraints exclude THS4561, and bandwidth requirements exceed ADA4940 capability.

FAQ

What is the maximum operating temperature for the ADA4932-1YCPZ-R2?

The ADA4932-1YCPZ-R2 is specified to operate from −40°C to +105°C ambient temperature. This extended industrial temperature range ensures reliable performance in harsh environments such as base station radios, motor control systems, and medical imaging equipment where thermal management is challenging. The 16-lead LFCSP package with exposed paddle helps maintain junction temperature below 150°C under typical load conditions.

Can the ADA4932-1YCPZ-R2 be used with single-supply operation?

Yes, the ADA4932-1YCPZ-R2 supports single-supply operation from +3 V to +11 V (e.g., +5 V/0 V). In 5 V operation, it delivers 560 MHz −3 dB bandwidth, 2200 V/µs slew rate, and 10 ns 0.1% settling time. The input common-mode range extends from −VS + 0.2 V to +VS − 1.8 V, and VOCM can be biased at mid-supply (e.g., 2.5 V) to match ADC input requirements - all confirmed in Table 4 of the Rev. F datasheet.

How does the VOCM pin function in the ADA4932-1YCPZ-R2?

The VOCM pin in the ADA4932-1YCPZ-R2 directly controls the output common-mode voltage with 0.998 V/V gain and 270 MHz small-signal bandwidth. Applying 2.5 V to VOCM forces the average of +OUT and −OUT to 2.5 V, enabling seamless interfacing with ADCs requiring specific input common-mode levels. This internal feedback loop also enhances output balance, suppressing even-order harmonics without requiring matched external components.

What is the power-down behavior of the ADA4932-1YCPZ-R2?

When the PD pin is driven to ≤(+VS − 2.8) V, the ADA4932-1YCPZ-R2 enters power-down mode, reducing quiescent current to 1.0 mA (typical). Turn-off time is 1100 ns; turn-on time is 16 ns. During shutdown, output impedance rises and differential output is disabled, preventing signal injection into downstream circuits - critical for multiplexed or shared ADC input architectures.

Is the ADA4932-1YCPZ-R2 pin-compatible with the AD8132?

No, the ADA4932-1YCPZ-R2 is not pin-compatible with the AD8132. While both are differential amplifiers, the ADA4932-1YCPZ-R2 uses a 16-lead LFCSP with dedicated +VS/−VS power pins (pins 5–8 and 13–16), VOCM (pin 9), and separate +FB/−FB (pins 1 and 4), whereas the AD8132 uses an 8-lead SOIC or MSOP with different pin assignments and no VOCM control. Layout redesign is required for migration.
