Product details
Overview
AD8075ARU-REEL from Analog Devices is a triple-channel, high-speed video buffer with fixed gain of +2, designed for RGB signal conditioning in display interfaces. It delivers 500 MHz –3 dB bandwidth at 2 Vp-p, 1350 V/µs slew rate, <4 ns settling time, and 0.01% differential gain error - enabling high-fidelity analog video routing in LCD/plasma displays and video routers.
For engineers reviewing the AD8075ARU-REEL datasheet, AD8075ARU-REEL pinout, AD8075ARU-REEL application, or AD8075ARU-REEL equivalent, key selection criteria include its G = +2 gain architecture, TSSOP-16 package compatibility, high-impedance disable functionality, and verified performance under ±5 V dual supply with 150 Ω load.
Technical Context
The AD8075ARU-REEL implements three independent voltage-feedback amplifier channels, each internally configured for precise G = +2 operation via a dedicated feedback network isolated during disable mode. Its folded-cascode output stage with emitter-follower buffering enables 2.2 V output swing headroom from rails into 150 Ω loads.
It features TTL-compatible OE control that places all outputs in high-impedance state with 90 dB off-isolation at 10 MHz and reduces quiescent current to ≤5.5 mA. The architecture maintains <0.01° differential phase error and –80 dB all-hostile crosstalk at 10 MHz, critical for multi-channel RGB integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed +2 (non-inverting), enabling signal amplitude restoration after 75 Ω series termination in video distribution. |
| –3 dB Bandwidth | 500 MHz at 2 Vp-p, RL = 150 Ω - supports full HD and UXGA video timing without attenuation. |
| Slew Rate | 1350 V/µs - ensures faithful reproduction of fast video edges without distortion. |
| Settling Time | 4 ns to 0.1% - meets tight pixel clock timing budgets in high-resolution displays. |
| Differential Gain/Phase | 0.01% / 0.01° - preserves color fidelity in NTSC/PAL and RGB analog video paths. |
| Off Isolation | 90 dB at 10 MHz - prevents signal leakage between disabled and active channels in multiplexer configurations. |
| Supply Current | ≤30 mA (all on), ≤5.5 mA (all off) - enables low-power standby in multi-buffer systems. |
Pinout & Package
AD8075ARU-REEL is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP, RU-16), 4.4 mm × 5.0 mm body, 0.65 mm pitch, with exposed pad not electrically connected. Thermal resistance θJA = 150.4°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Digital enable input | TTL-compatible control: logic low enables outputs; logic high disables all three outputs to high-Z. |
| 2 (DGND) | Digital ground reference | Reference for OE logic threshold (0.8 V / 2.0 V); must be tied to system digital ground plane. |
| 3 (IN2) | Channel 2 analog input | High-impedance (10 MΩ), low-capacitance (1.5 pF) input for third video channel (e.g., blue). |
| 4 (AGND) | Analog ground reference | Reference for input transconductance stage and internal gain network; requires separate low-noise AGND plane. |
| 5 (IN1) | Channel 1 analog input | Independent high-Z input for second video channel (e.g., green). |
| 6 (AGND) | Analog ground reference | Second AGND pin for improved grounding symmetry across input stage. |
| 7 (IN0) | Channel 0 analog input | Independent high-Z input for first video channel (e.g., red). |
| 8 (VEE) | Negative supply rail | Accepts –4.5 V to –5.5 V; output swing extends to –VEE + 2.2 V into 150 Ω. |
| 9–10 (VCC) | Positive supply rail (dual pins) | Accepts +4.5 V to +5.5 V; dual pins reduce supply inductance for high-frequency stability. |
| 11 (OUT2) | Channel 2 analog output | Low-impedance (0.5 Ω enabled) voltage source; supports series 75 Ω termination for coaxial video routing. |
| 12 (VEE) | Negative supply rail (second pin) | Second VEE pin for enhanced power delivery and reduced ground bounce. |
| 13 (OUT1) | Channel 1 analog output | Matched output drive capability to OUT0/OUT2; maintains inter-channel gain matching ≤±0.2%. |
| 14 (VCC) | Positive supply rail (third pin) | Third VCC connection improves decoupling effectiveness at high frequencies. |
| 15 (OUT0) | Channel 0 analog output | Primary output for red channel; same electrical specs as OUT1/OUT2, including 90 dB off-isolation. |
| 16 (VEE) | Negative supply rail (third pin) | Third VEE pin ensures symmetrical current return paths for all three output stages. |
Key Features
| Feature | Design Value |
|---|---|
| G = +2 fixed gain architecture | Compensates for 6 dB loss in double-terminated 75 Ω video lines, eliminating need for external gain-setting resistors. |
| High-impedance disable mode | Outputs reach ≥3.5 MΩ off-state impedance, enabling clean bus-sharing in RGB multiplexers without loading active channels. |
| All-hostile crosstalk suppression | –80 dB at 10 MHz ensures minimal interference between R/G/B channels even when driven with dissimilar signals. |
| Video-optimized DC accuracy | ±0.2% max gain error and 27 µV max input offset support accurate color balance in professional display calibration. |
| Robust output short-circuit protection | 70 mA current limit with automatic recovery prevents latch-up or damage during cable fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8074ARU-REEL | G = +1 unity-gain configuration; 1600 V/µs slew rate; 600 MHz bandwidth at 200 mVp-p. | Used where signal amplitude preservation (not restoration) is required, e.g., direct RGB routing without termination loss. | Select AD8074ARU-REEL when driving 75 Ω loads with source-series termination only, avoiding gain-induced noise amplification. |
| THS3201DGN | Single-channel, 1.8 GHz bandwidth, ±15 V supply capable; no integrated disable function; higher quiescent current (12 mA/channel). | Requires three separate devices and external logic for tri-state control; suited for wide-supply industrial video systems. | Choose THS3201DGN only when >1 GHz bandwidth or >±10 V output swing is mandatory, accepting added complexity and power. |
Compared with AD8074ARU-REEL and THS3201DGN, AD8075ARU-REEL uniquely combines G = +2 gain, integrated OE control, and 500 MHz bandwidth in a single 16-pin TSSOP - optimizing board space, power, and signal integrity for standard-definition to high-definition RGB distribution.

FAQ
What is the operating supply voltage range for AD8075ARU-REEL?
The AD8075ARU-REEL operates from dual supplies of ±4.5 V to ±5.5 V. It supports single-supply operation at 10 V with AGND referenced near midsupply, but the recommended configuration uses ±5 V for optimal video performance. Supply voltages beyond ±5.5 V risk exceeding absolute maximum ratings and may cause permanent damage.
Does AD8075ARU-REEL support DC-coupled RGB signal paths?
Yes, AD8075ARU-REEL supports DC-coupled operation with input voltage range of ±1.4 V (relative to AGND) and output swing extending to within 2.2 V of either rail into 150 Ω. This allows full-range RGB signal transmission without AC coupling capacitors, preserving black-level accuracy and eliminating low-frequency droop in static image displays.
How does the OE pin behave during power-up sequencing?
The OE pin defaults to high-impedance (disabled) state when unconnected or floating, but Analog Devices recommends actively driving OE to logic high (≥2.0 V) during power-up to ensure predictable output behavior. With OE high, all outputs enter high-Z mode consuming ≤5.5 mA, preventing unintended signal contention on shared video buses before system initialization completes.
Can AD8075ARU-REEL drive 75 Ω coaxial cables directly?
Yes, AD8075ARU-REEL is optimized for 75 Ω video loads: its output stage delivers 2 Vp-p into 150 Ω (equivalent to 75 Ω double-terminated), and its 0.5 Ω enabled output impedance allows clean series termination with 75 Ω resistors. For best results, place the 75 Ω resistor adjacent to the AD8075ARU-REEL output pin and route the coaxial cable with controlled impedance.
What thermal considerations apply to AD8075ARU-REEL in continuous operation?
At maximum ambient temperature (+85°C) and full power (30 mA, ±5 V), AD8075ARU-REEL dissipates ~300 mW. With θJA = 150.4°C/W, junction temperature reaches ~128°C - below the 150°C glass transition limit. To ensure reliability, use ≥2 cm² copper pour under the exposed pad area and maintain airflow; derate power linearly above 70°C ambient per Figure 1 in the datasheet.
