Product details
Overview
ADA4860-1YRJZ-RL7 from Analog Devices is a single-channel, current-feedback operational amplifier optimized for high-speed video and broadband signal conditioning. It delivers 800 MHz −3 dB bandwidth (G = +1, ±5 V), 790 V/μs slew rate, 8 ns settling time to 0.5%, 0.02% differential gain, and 0.02° differential phase - enabling precision analog video distribution in consumer and professional systems.
For engineers reviewing the ADA4860-1YRJZ-RL7 datasheet, ADA4860-1YRJZ-RL7 pinout, ADA4860-1YRJZ-RL7 application, or ADA4860-1YRJZ-RL7 equivalent, key selection criteria include its 6-lead SOT-23 package, power-down capability (0.25 mA quiescent current), ±5 V / +5 V supply flexibility, and verified performance driving 75 Ω video loads with <0.1 dB flatness to 125 MHz.
Technical Context
The ADA4860-1YRJZ-RL7 uses a current-feedback architecture with 90 Ω inverting-input impedance and 12 MΩ noninverting-input resistance, enabling stable high-gain configurations up to +10 while maintaining wide bandwidth. Its transimpedance open-loop gain exceeds 700 kΩ at 25°C, supporting fast closed-loop response with minimal phase shift.
It integrates a dedicated POWER DOWN pin referenced to −VS, enabling logic-compatible shutdown (threshold: −VS + 0.5 V) with 200 ns turn-on and 3.5 μs turn-off times. The device operates across −40°C to +105°C and supports both single-supply (+5 V) and dual-supply (±5 V) configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 800 MHz at G = +1, ±5 V - enables full HD/3G-SDI baseband signal amplification without attenuation |
| Slew Rate | 790 V/μs (falling edge, ±5 V) - supports clean 2 Vp-p transient response at >100 MHz |
| Settling Time | 8 ns to 0.5% for 2 V step - ensures accurate pixel-level timing in video line drivers |
| Differential Gain/Phase | 0.02% / 0.02° at 150 Ω load - meets SMPTE 253M broadcast video fidelity requirements |
| Supply Current | 6 mA enabled, 0.25 mA in power-down - reduces thermal load in multi-channel video systems |
| Input Offset Voltage | ±13 mV max - allows DC-coupled video paths with minimal baseline shift |
| Output Drive | ±3.1 V swing into 150 Ω - sustains 1 Vrms video signal integrity over standard coaxial cable |
Pinout & Package
The ADA4860-1YRJZ-RL7 is housed in a 6-lead SOT-23 (RJ-6) package with exposed pad for thermal enhancement, compatible with JEDEC-standard reflow profiles and rated for 170°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Amplifier output | Delivers rail-to-rail capable voltage swing; requires series 75 Ω termination for video impedance matching |
| –VS (Pin 2) | Negative supply rail | Reference for POWER DOWN threshold; must be connected even in single-supply operation |
| +IN (Pin 3) | Noninverting input | High-impedance (12 MΩ) node; used for video sync tip clamping or DC restoration circuits |
| –IN (Pin 5) | Inverting input | Low-impedance (90 Ω) current-feedback node; sets closed-loop gain with RF/RG network |
| POWER DOWN (Pin 5) | Shutdown control | Active-high logic input referenced to –VS; pulls supply current to 0.25 mA when driven > (–VS + 0.5 V) |
| +VS (Pin 6) | Positive supply rail | Accepts 5 V to 12 V; bypassing requires 0.1 μF MLCC ≤ 3 mm from pin and 10 μF tantalum nearby |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Higher 1.8 GHz bandwidth but no power-down pin; 12.5 mA quiescent current vs. 6 mA | Lacks integrated shutdown - requires external enable circuitry for power-gated video paths | Select when maximum bandwidth is critical and continuous operation is acceptable |
| THS3201DGN | Lower 1.8 GHz bandwidth, higher 17 mA supply current, and no differential phase spec below 0.1° | Not characterized for broadcast video standards; limited 0.1 dB flatness (≤60 MHz) | Select only for non-video high-speed analog front-ends where video fidelity is not required |
Compared with LMH6702MF/NOPB and THS3201DGN, the ADA4860-1YRJZ-RL7 uniquely combines broadcast-grade video performance (0.02° phase), integrated power-down, and SOT-23 footprint - making it optimal for space-constrained, power-aware video routing designs.

FAQ
What is the maximum operating temperature range for the ADA4860-1YRJZ-RL7?
The ADA4860-1YRJZ-RL7 is specified to operate from −40°C to +105°C ambient temperature, validated across the full range for parameters including bandwidth, slew rate, and differential phase. This extended temperature grade supports deployment in industrial video encoders, automotive infotainment head units, and outdoor broadcast equipment without derating.
Does the ADA4860-1YRJZ-RL7 require external compensation for stability?
No, the ADA4860-1YRJZ-RL7 is internally compensated for unity-gain stability and does not require external capacitors or resistors to maintain phase margin. Its current-feedback architecture ensures unconditional stability with recommended feedback resistor values (e.g., 499 Ω for G = +2), as confirmed in Figure 56 and Figure 57 of the datasheet.
Can the ADA4860-1YRJZ-RL7 drive a 75 Ω coaxial cable directly?
Yes, the ADA4860-1YRJZ-RL7 can drive 75 Ω coaxial cable directly when configured with a series 75 Ω output resistor (as shown in Figure 55), achieving 0.02% differential gain and 0.02° differential phase. This configuration maintains impedance match, minimizes reflections, and preserves video signal fidelity over distances up to 100 meters.
What is the typical input voltage noise of the ADA4860-1YRJZ-RL7 at 100 kHz?
The typical input voltage noise of the ADA4860-1YRJZ-RL7 is 4.0 nV/√Hz at 100 kHz, measured under ±5 V supply conditions. This low noise floor supports high-resolution signal conditioning in applications such as ultrasound front-ends and precision test equipment where SNR preservation is critical.
How does the POWER DOWN pin function in single-supply operation?
In single-supply operation (+5 V, −VS = 0 V), the POWER DOWN pin activates when driven above 0.5 V (i.e., −VS + 0.5 V). Leaving the pin open or grounding it enables normal operation. This logic-level compatibility allows direct interfacing with 1.8 V or 3.3 V microcontrollers without level-shifting circuitry.
