Product details
Overview
AD8075ARU from Analog Devices is a triple-channel, high-speed video buffer with fixed gain of +2 per channel, designed for RGB signal conditioning in LCD/plasma displays and video routing systems. It delivers 500 MHz (–3 dB) large-signal bandwidth at 2 Vp-p, 1350 V/µs slew rate, <4 ns settling time to 0.1%, and 90 dB output disable isolation at 10 MHz - enabling clean, low-distortion distribution of high-resolution video signals.
For engineers reviewing the AD8075ARU datasheet, AD8075ARU pinout, AD8075ARU application, or AD8075ARU equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed use cases in RGB buffering and multiplexing, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The AD8075ARU implements three independent, fully buffered voltage amplifier channels, each configured as a non-inverting gain-of-two stage using internal precision feedback resistors. Its architecture employs NPN transconductance input stages and folded-cascode emitter-follower outputs, optimized for driving 75 Ω reverse-terminated video loads with 0.01% differential gain error and 0.01° differential phase error at 3.58 MHz.
Each channel features TTL-compatible OE control that places outputs into high-impedance state (3.5–7.5 MΩ disabled output resistance), reducing quiescent current from 24 mA (all on) to 4 mA (all off). The device uses separate analog ground (AGND) and digital ground (DGND) pins to isolate sensitive analog signal paths from logic switching noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +2 per channel (fixed, internal feedback network; no external resistor required) |
| –3 dB Bandwidth | 500 MHz @ 2 Vp-p, RL = 150 Ω (supports full HD/UXGA video timing without attenuation) |
| Slew Rate | 1350 V/µs (enables faithful reproduction of fast video edges without distortion) |
| Settling Time | 4 ns to 0.1% (ensures pixel-level accuracy in high-refresh-rate displays) |
| Differential Gain/Phase | 0.01% / 0.01° @ 3.58 MHz (meets broadcast-grade NTSC/PAL color fidelity requirements) |
| Off Isolation | 90 dB @ 10 MHz (prevents crosstalk leakage between disabled and active channels in mux applications) |
| Supply Range | ±4.5 V to ±5.5 V (dual supply only; not rated for single-supply operation without AGND biasing) |
Pinout & Package
AD8075ARU is housed in a 16-lead TSSOP (RU-16) package, 5.0 mm × 4.4 mm × 1.2 mm, with 0.65 mm lead pitch and exposed thermal pad (not electrically connected). Pin 1 marked by dot; pin numbering counterclockwise from top-left corner when viewed component-side up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Digital enable input | TTL-compatible control: logic low (≤0.8 V) enables all three outputs; logic high (≥2.0 V) disables outputs to high-Z state |
| 2 (DGND) | Digital ground reference | Return path for OE logic; must be isolated from AGND except at single-point star ground to prevent noise coupling |
| 3 (IN2) | Channel 2 analog input | High-impedance (10 MΩ), low-capacitance (1.5 pF) input for third video signal (e.g., blue) |
| 4 (AGND) | Analog ground reference | Reference for all analog inputs, outputs, and internal gain network; requires dedicated low-noise ground plane |
| 5 (IN1) | Channel 1 analog input | Identical to IN2; used for second video signal (e.g., green) |
| 6 (AGND) | Analog ground reference | Second AGND pin for improved grounding; connects internally to same analog ground node as Pin 4 |
| 7 (IN0) | Channel 0 analog input | Identical to IN2; used for first video signal (e.g., red) |
| 8 (VEE) | Negative supply rail | Connects to –5 V supply; output swing limited to –VS + 2.2 V (min) into 150 Ω load |
| 9 (VCC) | Positive supply rail | Connects to +5 V supply; output swing limited to +VS – 2.2 V (min) into 150 Ω load |
| 10 (VCC) | Positive supply rail | Second VCC pin for reduced power supply inductance; must be decoupled independently |
| 11 (OUT2) | Channel 2 analog output | Low-output-impedance (<0.5 Ω enabled) voltage source; requires series 75 Ω termination for 75 Ω cable drive |
| 12 (VEE) | Negative supply rail | Second VEE pin for reduced power supply inductance; must be decoupled independently |
| 13 (OUT1) | Channel 1 analog output | Identical to OUT2; used for second video output (e.g., green) |
| 14 (VCC) | Positive supply rail | Third VCC pin; completes triple-supply-pin configuration for optimal high-frequency PSRR |
| 15 (OUT0) | Channel 0 analog output | Identical to OUT2; used for first video output (e.g., red) |
| 16 (VEE) | Negative supply rail | Third VEE pin; completes triple-supply-pin configuration for symmetric current return paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8074ARUZ-REEL7 | G = +1 (unity gain); 600 MHz small-signal BW vs. AD8075ARU's 500 MHz; 1600 V/µs slew rate | Preferred for impedance buffering (e.g., fan-out to multiple 75 Ω loads) without signal amplification; lower power (21.5 mA typ) | Select AD8074ARUZ-REEL7 when gain-of-one signal replication is required and higher slew rate is beneficial for edge fidelity. |
| THS3201DGN | Single-channel, G = +1 only; 1.8 GHz BW; 6000 V/µs slew rate; SOIC-8 package | Requires three devices and external gain-setting resistors for triple-channel use; no integrated OE disable | Choose THS3201DGN only for ultra-wideband (>1 GHz) single-channel applications where AD8075ARU's integrated triple-channel + OE is unnecessary. |
Compared with AD8074ARUZ-REEL7 and THS3201DGN, the AD8075ARU uniquely combines fixed +2 gain, integrated OE control, matched triple-channel performance, and broadcast-grade video specs in one RU-16 package - making it irreplaceable for space-constrained RGB multiplexing and dual-monitor driver designs requiring gain compensation.

FAQ
What is the gain configuration of the AD8075ARU, and can it be changed?
The AD8075ARU has a fixed, internally set non-inverting gain of +2 per channel - no external resistors or configuration pins are required or supported. This gain is implemented via precision laser-trimmed feedback resistors on-die and cannot be altered. Attempting to modify gain externally will degrade stability, bandwidth, and video specifications. For unity-gain applications, use the pin-compatible AD8074ARU instead.
Does the AD8075ARU support single-supply operation?
No, the AD8075ARU is specified and characterized exclusively for dual-supply operation (±4.5 V to ±5.5 V). While the datasheet mentions theoretical single-supply adaptation (10 V with AGND biased at mid-rail), this mode is not tested, guaranteed, or recommended for production use. The AD8075ARU lacks rail-to-rail input/output capability and exhibits degraded distortion and settling performance outside its dual-supply operating range.
What is the purpose of the separate AGND and DGND pins on the AD8075ARU?
The AD8075ARU separates analog ground (AGND, Pins 4 & 6) and digital ground (DGND, Pin 2) to prevent noise coupling from the OE logic switch into sensitive analog signal paths. AGND serves as the reference for all analog inputs, outputs, and internal gain networks, while DGND references only the OE input threshold. These grounds must connect at a single point - typically near the power supply decoupling capacitors - to avoid ground loops and preserve 0.01° differential phase accuracy.
How does the AD8075ARU achieve high OFF isolation while maintaining G = +2 gain?
The AD8075ARU uses an internal buffered feedback termination scheme: during OE = high, a dedicated low-impedance ground buffer disconnects the gain-setting feedback network from the output node, preventing resistive loading. Both the main output stage and this buffer enter high-impedance state simultaneously, achieving 3.5–7.5 MΩ disabled output resistance and 90 dB isolation - unlike conventional G = +2 amplifiers where feedback resistors would otherwise dominate and limit OFF impedance.
Can the AD8075ARU drive 50 Ω transmission lines, or is it limited to 75 Ω?
The AD8075ARU is optimized for 75 Ω video loads (e.g., RGB coax, composite video), with output voltage swing and distortion specs guaranteed into 150 Ω (parallel 75 Ω) and 1 kΩ. Driving 50 Ω directly causes excessive current draw (>40 mA per channel), thermal stress, and degraded distortion (e.g., >0.05% differential gain). For 50 Ω systems, add a 25 Ω series resistor to match - but verify signal integrity, as bandwidth drops to ~350 MHz (large-signal) under that load.
