Product details
Overview
ADA4930-1SCPZ-EPR2 from Analog Devices is an ultralow-noise, high-speed differential amplifier optimized as an ADC driver for 1.8 V, up to 14-bit converters operating from DC to 70 MHz. It delivers 1.2 nV/√Hz input voltage noise, −104 dBc HD2 at 10 MHz (5 V supply), and 3400 V/µs slew rate, enabling high-fidelity signal conditioning in defense-grade data acquisition systems.
For engineers reviewing the ADA4930-1SCPZ-EPR2 datasheet, ADA4930-1SCPZ-EPR2 pinout, ADA4930-1SCPZ-EPR2 application, or ADA4930-1SCPZ-EPR2 equivalent, key selection criteria include its −55°C to +105°C extended temperature range, adjustable VOCM for ADC input alignment, fast 1.5 ns overdrive recovery, and SiGe-based distortion performance critical for IF/baseband gain blocks.
Technical Context
The ADA4930-1SCPZ-EPR2 employs a fully differential architecture with internal common-mode feedback that enforces output balance and suppresses even-order harmonics. Its dual-loop design separates differential gain control (via external RF/RG) from common-mode level setting (via VOCM pin), supporting both single-ended-to-differential and differential-to-differential configurations.
It operates from 3.3 V or 5 V supplies with independent power-down (PD) control, delivering 380 MHz 0.1 dB gain flatness and 1.35 GHz −3 dB bandwidth (G = 1, 5 V). The SiGe process ensures stable 1.2 nV/√Hz noise across −55°C to +105°C while maintaining <3.1 mV input offset voltage over temperature.
Key Specifications

| HD2/HD3 @ 10 MHz | −104/−101 dBc (5 V) - preserves SFDR in baseband and low-IF receiver stages |
| Slew Rate | 3400 V/µs - handles fast transient signals without slewing-induced distortion |
| Overdrive Recovery | 1.5 ns - minimizes dead time after large-signal overload in burst-mode systems |
| Operating Temp Range | −55°C to +105°C - qualified for aerospace, defense, and harsh-environment industrial use |

Pinout & Package
The ADA4930-1SCPZ-EPR2 is housed in a 3 mm × 3 mm, 16-lead LFCSP (CP-16-35) with exposed thermal paddle. Pin layout prioritizes symmetry and routing simplicity to minimize imbalance-induced distortion.

| 2 (+IN), 3 (−IN) | Differential input summing nodes | Accept single-ended or differential input; input CMVR: 0.3 V to 2.8 V (5 V) |
| 4 (+FB) | Positive feedback node | Completes symmetrical feedback path for balanced gain configuration |
| 5–8, 13–16 (+VS/−VS) | Power supply terminals | Four dedicated +VS and four −VS pins reduce supply impedance and improve PSRR |
| 9 (VOCM) | Output common-mode control | DC voltage sets output CM level; gain = 1.01 V/V, ±0.02 V error over temp |
| 10 (+OUT), 11 (−OUT) | Differential output drivers | Deliver rail-to-rail swing into 200 Ω loads; balance error ≤55 dB at 1 MHz |
| 12 (PD) | Power-down enable | Logic-high (>3 V on 5 V supply) disables amplifier, reducing quiescent current to 2.6 mA |
| EPAD | Thermal paddle | Not electrically connected; must be soldered to PCB ground/power plane for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ADC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4932-1ACPZ-R7 | Lower bandwidth (650 MHz), higher noise (2.3 nV/√Hz), commercial temp range only (−40°C to +85°C) | Not qualified for defense/aerospace; unsuitable for >85°C operation or ultra-low-noise 14-bit ADCs | Select only for cost-sensitive commercial designs where extended temp and sub-1.3 nV/√Hz noise are not required. |
| THS4561IRGET | Higher power (45 mA vs. 34 mA), lower HD2 (−92 dBc @ 10 MHz), no power-down pin | Lacks PD function and AQEC support; VOCM range limited to 0.25 V to VCC − 0.25 V | Choose when integrated shutdown is unnecessary and THS4561's 1.8 nV/√Hz noise meets system SNR goals. |
Compared with ADA4932-1ACPZ-R7 and THS4561IRGET, the ADA4930-1SCPZ-EPR2 uniquely combines defense-grade temperature range, SiGe-level distortion performance, and VOCM accuracy-making it irreplaceable in mission-critical, high-dynamic-range ADC interfaces where parametric consistency across extreme conditions is non-negotiable.

FAQ
What is the supply voltage range supported by the ADA4930-1SCPZ-EPR2?
The ADA4930-1SCPZ-EPR2 operates from either 3.3 V or 5 V single-supply configurations, with absolute maximum supply rating of 5.5 V. At 5 V, it achieves optimal dynamic performance-including 3400 V/µs slew rate and −104 dBc HD2 at 10 MHz-while maintaining full functionality across its −55°C to +105°C operating range. Quiescent current is 34 mA typical per amplifier when enabled.
How does the VOCM pin function in the ADA4930-1SCPZ-EPR2?
The VOCM pin on the ADA4930-1SCPZ-EPR2 sets the output common-mode voltage with high precision: gain is 0.99–1.02 V/V and input offset voltage remains within ±31 mV over temperature. For a 5 V supply, VOCM accepts 0.5 V to 2.3 V, allowing exact alignment with 1.8 V ADC inputs. This direct control eliminates external level-shifting circuitry and preserves SNR by maximizing ADC input dynamic range.
Is the ADA4930-1SCPZ-EPR2 pin-compatible with other members of the ADA4930 family?
Yes-the ADA4930-1SCPZ-EPR2 shares identical 16-lead LFCSP (CP-16-35) packaging, pinout, and footprint with the ADA4930-1-EP and ADA4930-2-EP variants. All share the same pin functions including PD, VOCM, dual +VS/−VS rails, and symmetric feedback architecture-enabling drop-in replacement within the same family for single-channel versus dual-channel board revisions.
What is the thermal design guidance for the ADA4930-1SCPZ-EPR2?
The ADA4930-1SCPZ-EPR2 uses a thermally enhanced 3 mm × 3 mm LFCSP with exposed paddle (θJA = 81.6 °C/W on JEDEC 4-layer board). To maintain junction temperature below 150°C, the EPAD must be soldered to a low-thermal-resistance copper plane-ideally connected to ground or power via multiple thermal vias. Figure 3 in the datasheet defines maximum safe power dissipation vs. ambient temperature under these conditions.
Does the ADA4930-1SCPZ-EPR2 support single-ended input operation?
Yes-the ADA4930-1SCPZ-EPR2 supports both single-ended-to-differential and differential-to-differential configurations. With single-ended input, +IN is driven while −IN is terminated to a reference voltage (e.g., VOCM), and external resistive feedback sets gain. The internal common-mode feedback loop automatically balances outputs and rejects even-order distortion, making it ideal for legacy signal sources interfacing to modern differential ADCs.
