Product details
Overview
AD8044ARZ-14 from Analog Devices is a quad, rail-to-rail output, voltage-feedback high-speed operational amplifier optimized for +3 V, +5 V, and ±5 V supplies. It delivers 150 MHz –3 dB bandwidth (G = +1), 170 V/µs slew rate, and output swing within 25 mV of either rail - enabling full dynamic range in video buffering, A/D driver, and active filter applications.
For engineers reviewing the AD8044ARZ-14 datasheet, AD8044ARZ-14 pinout, AD8044ARZ-14 application, or AD8044ARZ-14 equivalent, key selection criteria include guaranteed rail-to-rail output drive into 150 Ω, differential gain error ≤ 0.06%, settling time to 0.1% in 40 ns, and operation across –40°C to +85°C with Pb-free SOIC-14 packaging.
Technical Context
The AD8044ARZ-14 employs Analog Devices' eXtra-Fast Complementary Bipolar (XFCB) process, integrating PNP/NPN transistors with fT up to 4 GHz and dielectric isolation to suppress latch-up. Its differential-input stage minimizes nonlinear junction capacitance effects, achieving –68 dBc THD at 5 MHz and 0.1 dB gain flatness to 12 MHz.
A complementary common-emitter output stage enables 30 mA output current with outputs within 0.5 V of supply rails. Input common-mode range extends 200 mV below V– and within 1 V of V+, with no phase reversal when inputs exceed rails by 1 V - critical for single-supply RGB video and CCD imaging interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 150 MHz at G = +1: supports high-definition video signal paths and >10 MSPS ADC driving without bandwidth limitation. |
| Slew Rate | 170 V/µs: ensures faithful reproduction of fast transient signals such as ultrasound pulses or digital video edges. |
| Output Swing | Within 25 mV of rails (RL = 10 kΩ): maximizes signal headroom in low-voltage portable systems using +3.3 V or +5 V supplies. |
| Differential Gain/Phase Error | 0.06% / 0.15° (NTSC, RL = 150 Ω): meets broadcast-grade video fidelity requirements without external calibration. |
| Supply Current | 13.1 mA max (quad): 3.275 mA per amplifier - enables battery-powered multichannel instrumentation with thermal efficiency. |
| Input Voltage Range | –0.2 V to +4 V (VS = +5 V): accepts ground-referenced RGB or composite video inputs without level-shifting circuitry. |
| Settling Time | 40 ns to 0.1% (G = –1, 2 V step): satisfies timing-critical sampling in high-speed data acquisition front-ends. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of Amplifier A; high-impedance node requiring guarded layout to preserve 150 MHz bandwidth. |
| 2 | +IN A | Non-inverting input of Amplifier A; supports common-mode input down to –0.2 V (V–) for true single-supply operation. |
| 3 | OUT A | Rail-to-rail output of Amplifier A; capable of sourcing/sinking 30 mA while maintaining <25 mV saturation voltage. |
| 4 | V– | Negative supply pin; connects to ground (single-supply) or –5 V (dual-supply); must be bypassed with 0.1 µF ceramic capacitor. |
| 5 | –IN B | Inverting input of Amplifier B; electrically isolated from other inputs to maintain >60 dB crosstalk suppression at 5 MHz. |
| 6 | +IN B | Non-inverting input of Amplifier B; shares same input specs as Pin 2 - validated for –0.2 V to +4 V common-mode range. |
| 7 | OUT B | Rail-to-rail output of Amplifier B; identical drive capability and settling performance as OUT A (Pin 3). |
| 8 | OUT D | Rail-to-rail output of Amplifier D; pin-compatible with OUT A/B/C for modular PCB layout reuse across all four channels. |
| 9 | –IN D | Inverting input of Amplifier D; matches AC/DC specs of Pins 1 and 5 - confirmed via AD8044A characterization data. |
| 10 | +IN D | Non-inverting input of Amplifier D; supports same input overvoltage tolerance (±3.4 V differential) as all other inputs. |
| 11 | OUT C | Rail-to-rail output of Amplifier C; verified 30 mA drive into 150 Ω with 0.55–4.4 V swing at +2.5 V reference. |
| 12 | –IN C | Inverting input of Amplifier C; exhibits <1.6 pF input capacitance - critical for stability with capacitive loads up to 40 pF. |
| 13 | +IN C | Non-inverting input of Amplifier C; matched bias current (2–4.5 µA) and offset voltage (1.0–9 mV) per AD8044A spec table. |
| 14 | V+ | Positive supply pin; operates from +3 V to +12 V or ±5 V; requires local 0.1 µF + 4.7 µF bypassing for high-frequency PSRR >70 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | 0.025 V to 2.98 V (RL = 10 kΩ, VS = +3 V) and –4.97 V to +4.97 V (VS = ±5 V): eliminates need for level-shifting in mixed-signal interfaces. |
| Single-supply input range | Extends 200 mV below V–: enables direct connection to ground-referenced video DACs or sensor outputs without clamping diodes. |
| No phase reversal on overdrive | Operates linearly with inputs up to 1 V beyond supply rails: prevents catastrophic signal inversion in transient-heavy medical imaging front-ends. |
| Low distortion at high frequency | –68 dBc THD at 5 MHz (G = +2, RL = 1 kΩ): preserves signal integrity in ultrasound beamforming and RF IF amplification. |
| Capacitive load drive | Stable with up to 40 pF (G = +2): supports direct driving of long coaxial cables or LCD column drivers without external isolation resistors. |
| Quad-channel integration | Four independent amplifiers in one SOIC-14: reduces board area by 60% vs. discrete dual op-amps in multichannel CCD readout systems. |

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 |
|---|---|---|---|
| AD8054ARZ-14 | Higher 220 MHz bandwidth, 270 V/µs slew rate, but 15.5 mA quiescent current per amplifier. | Better suited for >100 MSPS sampling systems; less optimal for battery-powered devices due to +18% power draw. | Select AD8054ARZ-14 only when bandwidth >180 MHz is required; AD8044ARZ-14 remains preferred for cost- and power-sensitive video/CCD designs. |
| LMH6624MA/NOPB | Lower 1.9 nV/√Hz noise, but 200 MHz bandwidth with 1000 V/µs slew rate; not rail-to-rail output (1.2 V min swing). | Superior for low-noise preamp stages; unsuitable for ground-swinging video or single-supply sensor interfaces. | Choose LMH6624MA/NOPB for ultra-low-noise analog front-ends where rail-to-rail output is unnecessary; AD8044ARZ-14 provides broader system compatibility. |
Compared with AD8044ARZ-14, AD8054ARZ-14 trades higher speed for increased power, while LMH6624MA/NOPB sacrifices rail-to-rail output and single-supply input range for lower noise - making AD8044ARZ-14 the balanced choice for multichannel video, imaging, and portable instrumentation.

FAQ
What supply voltages does the AD8044ARZ-14 support?
The AD8044ARZ-14 operates from single supplies of +3 V to +12 V, dual supplies of ±3 V to ±6 V, and is fully specified at +3 V, +5 V, and ±5 V. Its input common-mode range extends 200 mV below V– and within 1 V of V+, and its rail-to-rail output delivers full swing across this entire supply range - confirmed in AD8044 Rev. B datasheet Sections "Specifications" and "Product Description".
Is the AD8044ARZ-14 pin-compatible with the AD8041 or AD8042?
No, the AD8044ARZ-14 is not pin-compatible with AD8041 (single) or AD8042 (dual). AD8044ARZ-14 uses a 14-lead SOIC package with dedicated pins for four independent amplifiers (e.g., Pins 1–3 = Amp A, Pins 5–7 = Amp B, etc.), whereas AD8041 uses 8-lead SOIC and AD8042 uses 8-lead SOIC - different pin counts and assignments preclude direct substitution without PCB redesign.
Does the AD8044ARZ-14 support driving 75 Ω video loads directly?
Yes, the AD8044ARZ-14 drives 150 Ω loads with 0.55–4.4 V swing (VS = +5 V), and its 30 mA output current capability allows direct termination into 75 Ω with appropriate gain configuration. Application Figure 36 in the datasheet explicitly demonstrates RGB buffering into dual 75 Ω monitor loads using +3 V or +5 V supplies - confirming suitability for professional video distribution.
What is the maximum capacitive load the AD8044ARZ-14 can drive stably?
The AD8044ARZ-14 is characterized for stable operation with up to 40 pF capacitive load at G = +2, and 35 pF at G = +1 (AD8044A spec tables). Layout guidelines recommend series isolation resistors for loads >40 pF, and Figure 25 in the datasheet quantifies overshoot vs. capacitive load for multiple gain configurations - validating robust high-frequency drive capability.
How does the AD8044ARZ-14 perform in terms of power supply rejection?
The AD8044ARZ-14 delivers 70–80 dB PSRR across DC to 10 MHz (Figure 23), with +PSRR and –PSRR both exceeding 70 dB at 100 kHz. This ensures minimal supply noise coupling into sensitive analog paths - critical in mixed-signal systems where digital switching noise coexists with analog video or sensor signals on shared rails.
