Product details
Overview
AD8004AR-14 from Analog Devices is a quad current-feedback amplifier optimized for high-speed video and signal conditioning applications. It delivers 250 MHz –3 dB bandwidth (G = +1), 3000 V/µs slew rate, 21 ns settling to 0.1%, and 50 mA output drive in a 14-lead SOIC package - enabling precise analog signal routing in video switchers and active filters.
For engineers reviewing the AD8004AR-14 datasheet, AD8004AR-14 pinout, AD8004AR-14 application, or AD8004AR-14 equivalent, key selection criteria include single-supply operation (+4 V to +12 V), differential gain error of 0.04% (NTSC, RL = 150 Ω), and guaranteed performance across –40°C to +85°C industrial temperature range.
Technical Context
The AD8004AR-14 implements a two-stage current-feedback architecture with complementary bipolar process technology, enabling high dynamic range at low quiescent power (3.5 mA per amplifier). Its transimpedance-based open-loop gain (170–290 kΩ) and low inverting-input impedance (50 Ω) define frequency response independent of closed-loop gain - delivering constant bandwidth across gains when using appropriate feedback resistors.
It supports both inverting and noninverting configurations with recommended RF values from 499 Ω to 1.10 kΩ depending on gain and flatness requirements. Input common-mode voltage range extends to 3.2 V, and output swing reaches ±3.9 V into 150 Ω under ±2.5 V supply, making it suitable for driving legacy video loads and modern ADC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB, G = +1) | 250 MHz - supports full HD baseband video and fast pulse amplification without attenuation |
| Slew Rate | 3000 V/µs - enables faithful reproduction of large-amplitude, fast-edge signals (e.g., 2 V step in 1.8 ns) |
| Settling Time (0.1%) | 21 ns - meets timing budgets for 10-bit ADC drivers like AD876 operating at 20 MSPS |
| Differential Gain/Phase Error | 0.04% / 0.10° (NTSC, RL = 150 Ω) - preserves color fidelity in broadcast-quality video systems |
| Output Current | ±50 mA - drives 150 Ω video lines or multiple parallel loads without external buffering |
| Supply Range | +4 V to +12 V single supply or ±2.0 V to ±6.0 V dual supply - simplifies power design in portable and industrial equipment |
| Quiescent Current | 14 mA total (3.5 mA per amp) - enables low-power, multi-channel signal paths in battery-sensitive designs |
Pinout & Package
AD8004AR-14 is housed in a 14-lead SOIC (R-14) package per JEDEC MS-012AB, with 1.27 mm pitch, 8.75 mm × 4.00 mm body, and 1.75 mm max height. Pin 1 is marked by a notch or dot; top view orientation follows standard SOIC convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - connects directly to load or feedback network; capable of ±50 mA sourcing/sinking |
| 2 | Inverting Input A | Current-summing node for Amp A; low impedance (50 Ω) defines feedback path stability and bandwidth |
| 3 | Noninverting Input A | High-impedance input (2 MΩ) for Amp A; sets common-mode reference and DC bias point |
| 4 | +VS | Positive supply rail - accepts +4 V to +12 V (single) or +2.5 V to +6 V (dual); bypass with 0.1 µF ceramic capacitor |
| 5 | Noninverting Input B | High-impedance input for Amp B - electrically isolated from other inputs; used for independent channel configuration |
| 6 | Inverting Input B | Current-summing node for Amp B - requires matched feedback resistor placement to minimize parasitic capacitance |
| 7 | Output B | Amplifier B output - identical drive capability to Pin 1; shares +VS and –VS rails with other channels |
| 8 | –VS | Negative supply rail - grounded for single-supply operation; accepts –2.0 V to –6.0 V in dual mode |
| 9 | Output C | Amplifier C output - fully independent channel; layout symmetry critical to maintain crosstalk < –69 dB at 5 MHz |
| 10 | Inverting Input C | Current-summing node for Amp C - sensitive to stray capacitance; keep trace length < 2 mm for >100 MHz operation |
| 11 | Noninverting Input C | High-impedance input for Amp C - decoupled via local 0.1 µF capacitor to suppress noise coupling |
| 12 | Noninverting Input D | High-impedance input for Amp D - supports four-channel simultaneous signal processing in compact PCB area |
| 13 | Inverting Input D | Current-summing node for Amp D - requires same RF value as other channels for consistent gain flatness |
| 14 | Output D | Amplifier D output - completes quad functionality; all outputs specified for 150 Ω load and 0.1 dB flatness to 30 MHz |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8003ARZ-14 | Triple-channel version; identical specs per channel but lacks fourth amplifier | Suitable where only three high-speed paths are needed - saves cost and board area | Select AD8003ARZ-14 when system requires exactly three channels and lower total power (10.5 mA vs. 14 mA) |
| LMH6703MA/NOPB | Single-channel, higher slew rate (4000 V/µs), wider bandwidth (550 MHz), but higher quiescent current (6.5 mA) | Better for ultra-fast pulse applications (e.g., laser diode drivers), not quad integration | Choose LMH6703MA/NOPB when single-channel performance exceeds AD8004AR-14 and layout allows discrete placement |
Compared with AD8004AR-14, AD8003ARZ-14 offers identical per-channel performance in a triple configuration for reduced system count, while LMH6703MA/NOPB trades quad integration for superior single-channel speed and bandwidth - making AD8004AR-14 optimal for space-constrained, multi-channel video and instrumentation designs requiring balanced speed, power, and channel density.

FAQ
What is the maximum operating supply voltage for AD8004AR-14?
The AD8004AR-14 has an absolute maximum supply voltage rating of 12.6 V. For reliable continuous operation, Analog Devices specifies a maximum operating range of +4 V to +12 V for single-supply use and ±2.0 V to ±6.0 V for dual-supply configurations. Exceeding these limits risks permanent damage or parametric shift due to junction temperature rise beyond +150°C.
Does AD8004AR-14 support rail-to-rail output swing?
No, AD8004AR-14 does not provide rail-to-rail output swing. Into a 150 Ω load with ±2.5 V supplies, its output voltage swing is specified as ±3.9 V - meaning it cannot reach within ~0.1 V of either supply rail. With +5 V single supply, output swings from 0.9 V to 4.1 V, leaving ~0.9 V headroom at both extremes. This limitation must be accounted for in level-shifting circuits driving ADCs or video lines.
Can AD8004AR-14 drive a capacitive load directly?
AD8004AR-14 is not optimized for direct capacitive load driving. When driving loads with >10 pF capacitance, Analog Devices recommends adding a small series resistor (e.g., 5–25 Ω) between the output and the load to maintain stability and prevent peaking or ringing. Figure 6 and Figure 7 in the datasheet provide RSERIES vs. CL guidance - for example, 10 pF requires ~10 Ω, while 100 pF needs ~25 Ω to achieve ≤30 ns settling to 0.1%.
What is the input bias current specification for AD8004AR-14?
The AD8004AR-14 exhibits asymmetric input bias currents: –input bias current is ±35 µA (typical), +input bias current is ±40 µA (typical), both measured at +25°C. Over the full industrial temperature range (–40°C to +85°C), these increase to ±110 µA (–input) and ±115 µA (+input). These values reflect the current-feedback architecture's low-impedance inverting input and high-impedance noninverting input.
Is AD8004AR-14 RoHS compliant?
Yes, AD8004AR-14 is RoHS compliant. The "Z" suffix in the ordering code (e.g., AD8004ARZ-14) explicitly denotes lead-free, RoHS-compliant packaging per Analog Devices' product marking convention. This applies to the 14-lead SOIC (R-14) package with matte tin lead finish and halogen-free molding compound.
