Product details
Overview
ADA4927-1YCPZ-R2 from Analog Devices is a current-feedback differential amplifier optimized as an ultralow-distortion ADC driver for 16-bit converters up to 100 MHz. It delivers −105 dBc HD2 at 10 MHz, 2.3 GHz −3 dB bandwidth, 5000 V/µs slew rate, and adjustable output common-mode voltage (VOCM) with ±5 V or +5 V supply operation.
For engineers reviewing the ADA4927-1YCPZ-R2 datasheet, ADA4927-1YCPZ-R2 pinout, ADA4927-1YCPZ-R2 application, or ADA4927-1YCPZ-R2 equivalent, key selection criteria include harmonic distortion performance at RF/IF frequencies, VOCM control accuracy, power-down timing (400 ns turn-on), thermal resistance (87 °C/W), and LFCSP-16 package layout compatibility for high-speed differential signaling.
Technical Context
The ADA4927-1YCPZ-R2 employs a silicon-germanium complementary bipolar current-feedback architecture, delivering near-gain-independent loop gain for stable wideband operation. Its dual summing nodes (+IN/−IN) and symmetric feedback paths (+FB/−FB) enable precise differential gain configuration using external resistors while maintaining exceptional output balance via internal common-mode feedback.
This architecture achieves low input voltage noise (1.4 nV/√Hz), high open-loop transresistance (120–185 kΩ), and minimal even-order distortion suppression-critical for preserving SFDR in time-interleaved or pipeline ADC front-ends operating from dc to 100 MHz under ±5 V or single +5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 2300 MHz small-signal: supports wideband IF sampling without gain peaking or phase roll-off. |
| HD2 @ 10 MHz | −105 dBc: enables >16-bit ENOB in ADC systems with 10 MHz analog inputs. |
| Slew Rate | 5000 V/µs: ensures faithful reproduction of fast transient signals without slewing-induced distortion. |
| Input Voltage Noise | 1.4 nV/√Hz RTI: minimizes added noise floor when driving high-resolution ADCs. |

| 4 (+FB) | Positive feedback node | Completes current-feedback path; paired with −FB to define transimpedance gain. |
| 5–8 (+VS) | Positive supply terminals | Four parallel pins reduce supply inductance and improve PSRR at RF frequencies. |
| 9 (VOCM) | Output common-mode voltage control | DC-biased input sets differential output midpoint; bandwidth supports fast common-mode tracking. |
| 10 (+OUT) | Positive differential output | Low-impedance output optimized for 100 Ω differential termination into ADC inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ADC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4940-1ACPZ-R7 | Lower bandwidth (1 GHz), higher HD2 (−92 dBc @ 10 MHz), lower quiescent current (10.5 mA). | Better suited for battery-powered, lower-frequency (<50 MHz) precision data acquisition where power efficiency outweighs SFDR. | Select ADA4940-1ACPZ-R7 only when system bandwidth ≤ 50 MHz and thermal budget restricts >20 mA per channel. |

FAQ
What is the maximum recommended supply voltage for ADA4927-1YCPZ-R2?
The ADA4927-1YCPZ-R2 has an absolute maximum supply rating of 11 V total (e.g., +5.5 V/−5.5 V or +11 V/0 V), but its specified operating range is 4.5 V to 11.0 V. For optimal distortion performance and thermal safety, Analog Devices recommends operation within ±5 V (10 V total) or +5 V single-supply configurations as validated in the Rev. B datasheet. Exceeding ±5 V increases junction temperature and may degrade HD2/HD3 beyond −105 dBc/−103 dBc at 10 MHz.
How does the power-down (PD) pin function on ADA4927-1YCPZ-R2?
The PD pin on ADA4927-1YCPZ-R2 is a CMOS-compatible logic input: driving it below 1.8 V disables the amplifier, reducing quiescent current to 2.4 mA, while pulling it above 3.2 V enables full operation at 22.1 mA. The device achieves 400 ns turn-on time and 15 µs turn-off time, supporting rapid power gating in TDD systems. During power-down, both outputs enter high-impedance state, preventing signal feedthrough into downstream circuitry.
Can ADA4927-1YCPZ-R2 drive a 100 Ω differential load directly?
Yes, ADA4927-1YCPZ-R2 is characterized driving 1 kΩ and 200 Ω differential loads, and its output stage delivers 65 mA p-p linear current into matched 100 Ω differential terminations. The datasheet Figure 16 confirms stable large-signal frequency response up to 150 MHz with RL,dm = 200 Ω, and layout guidelines recommend symmetric 100 Ω source termination at the amplifier outputs to maintain S22 < −10 dB up to 1 GHz-ensuring minimal reflections into high-speed ADC inputs.
What is the purpose of the exposed pad (EPAD) on ADA4927-1YCPZ-R2?
The exposed pad (EPAD) on ADA4927-1YCPZ-R2 must be soldered to a PCB copper plane connected to any potential between +VS and −VS-typically tied to −VS for best thermal and noise performance. It reduces thermal resistance from junction-to-board by 30–40%, achieving the specified 87 °C/W θJA. Improper EPAD connection causes junction temperature rise >20°C at full load, degrading HD2 by up to 8 dB and risking reliability failure above 150°C.
Does ADA4927-1YCPZ-R2 support single-ended input operation?
Yes, ADA4927-1YCPZ-R2 supports robust single-ended-to-differential conversion: applying signal to +IN while holding −IN at a fixed bias (e.g., VOCM or mid-supply) generates fully balanced differential outputs. The datasheet Figure 43 shows this configuration with 301 Ω feedback resistors, achieving −105 dBc HD2 at 10 MHz. Input common-mode range extends to ±3.5 V under ±5 V supplies, allowing direct interface with 50 Ω single-ended sources without AC coupling.
