Product details
Overview
AD8044ARZ-14-REEL7 from Analog Devices is a quad, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed video and portable applications. It delivers 150 MHz –3 dB bandwidth (G = +1), 170 V/µs slew rate, and 40 ns settling time to 0.1% on +5 V supply, with output swing within 25 mV of either rail. It supports single-supply operation from +3 V to +12 V and is used in RGB video buffering, ultrasound channel amplification, and active filter stages.
For engineers reviewing the AD8044ARZ-14-REEL7 datasheet, AD8044ARZ-14-REEL7 pinout, AD8044ARZ-14-REEL7 application, or AD8044ARZ-14-REEL7 equivalent, key selection criteria include rail-to-rail output drive into 150 Ω loads, differential gain error ≤0.06%, NTSC video compliance, low 13.1 mA total quiescent current, and SOIC-14 packaging compatible with automated SMT assembly.
Technical Context
The AD8044ARZ-14-REEL7 employs Analog Devices' eXtra-Fast Complementary Bipolar (XFCB) process, enabling 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 0.06% differential gain error under NTSC conditions.
It features a complementary common-emitter output stage biased via internal current sources and common-mode feedback, delivering ±30 mA output current while maintaining rail-to-rail swing (e.g., 0.025 V to 2.98 V on +3 V supply into 10 kΩ). Input common-mode range extends 200 mV below V– and within 1 V of V+, with no phase reversal beyond supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 150 MHz at G = +1 - enables baseband video and ultrasound signal amplification without attenuation up to 12 MHz flatness (0.1 dB). |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of Amplifier A - referenced to local ground or feedback network; requires low-stray-capacitance layout for >100 MHz stability. |
| 2 | +IN A | Non-inverting input of Amplifier A - accepts DC-coupled video or sensor signals down to –0.2 V relative to V–. |
| 3 | OUT A | Output of Amplifier A - drives 150 Ω video loads or ADC inputs with rail-to-rail swing and <0.1% settling. |
| 4 | V– | Negative supply pin - connects to ground in single-supply mode; must be bypassed with 0.1 µF ceramic capacitor near pin. |
| 5 | +IN C | Non-inverting input of Amplifier C - identical electrical characteristics to Pins 2 and 10; enables independent channel configuration. |
| 6 | –IN C | Inverting input of Amplifier C - shares same noise and offset specs as Pin 1; used in inverting gain stages or active filters. |
| 7 | OUT C | Output of Amplifier C - electrically isolated from OUT A/B/D; crosstalk <–60 dB at 5 MHz ensures multichannel integrity. |
| 8 | V+ | Positive supply pin - accepts +3 V to +12 V; requires local 0.1 µF + bulk tantalum (≥4.7 µF) bypassing for transient load support. |
| 9 | –IN D | Inverting input of Amplifier D - supports high-frequency feedback networks; sensitive to parasitic capacitance (>1 pF degrades bandwidth). |

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 |
|---|---|---|---|
| AD8042ARZ-REEL7 | Dual-channel version; identical bandwidth (150 MHz), slew rate (170 V/µs), and rail-to-rail output, but only two amplifiers per SOIC-8 package. | Used when only two high-speed channels are required; saves board area but increases component count for quad-channel systems. | Select AD8042ARZ-REEL7 for dual-channel designs where footprint or cost-per-channel optimization outweighs integration benefits. |
| LMH6629MA/NOPB | Higher 1.5 GHz GBW and 3000 V/µs slew rate, but higher 12.5 mA per amplifier quiescent current and no guaranteed rail-to-rail output swing below 100 mV of rails. | Better suited for RF IF amplification or ultra-fast pulse conditioning, not NTSC video or low-voltage portable systems requiring true rail-to-rail swing. | Choose LMH6629MA/NOPB only when >500 MHz small-signal bandwidth is mandatory and power budget allows >2× higher per-channel current. |
Compared with AD8042ARZ-REEL7, AD8044ARZ-14-REEL7 provides 2× channel density in 75% more pins but reduces per-channel PCB real estate and inter-channel skew. Versus LMH6629MA/NOPB, AD8044ARZ-14-REEL7 trades raw speed for video-optimized linearity, lower power, and guaranteed rail-to-rail output-critical for battery-powered imaging and broadcast equipment.

FAQ
What supply voltage ranges does the AD8044ARZ-14-REEL7 support?
The AD8044ARZ-14-REEL7 operates from a single supply of +3 V to +12 V or dual supplies of ±3 V to ±6 V. It is fully specified at +3 V, +5 V, and ±5 V. Input common-mode range extends 200 mV below V– and within 1 V of V+, and output swings to within 25 mV of either rail under light loads - making AD8044ARZ-14-REEL7 ideal for single-rail portable video systems.
Does the AD8044ARZ-14-REEL7 meet NTSC video specifications?
Yes. The AD8044ARZ-14-REEL7 achieves 0.06% differential gain error and 0.15° differential phase error (NTSC, G = +2, RL = 150 Ω), along with 0.1 dB gain flatness to 12 MHz - satisfying SMPTE RP 145 and ITU-R BT.470 broadcast video fidelity requirements. These values are measured and guaranteed in the official AD8044 datasheet Rev. B, confirming AD8044ARZ-14-REEL7 suitability for professional camera and distribution amplifier designs.
Can the AD8044ARZ-14-REEL7 drive 150 Ω video loads directly?
Yes. The AD8044ARZ-14-REEL7 delivers ±30 mA output current and sustains rail-to-rail swing even into 150 Ω loads (e.g., 0.55 V to 4.4 V on +5 V supply). Its 170 V/µs slew rate and 40 ns 0.1% settling ensure minimal distortion on composite sync pulses and color burst signals - a key capability verified in AD8044ARZ-14-REEL7 characterization across temperature and supply conditions.
What is the maximum capacitive load the AD8044ARZ-14-REEL7 can drive stably?
The AD8044ARZ-14-REEL7 drives up to 40 pF capacitive loads with G = +2 while maintaining <30% overshoot, as confirmed in Figure 25 of the datasheet. For lower gains (e.g., G = +1), a series resistor (e.g., 10–40 Ω) is recommended to dampen peaking. Layout best practices - including ground plane isolation near inputs and tight feedback routing - are essential to preserve AD8044ARZ-14-REEL7 stability at full rated bandwidth.
Is the AD8044ARZ-14-REEL7 pin-compatible with other packages in the AD804x family?
Yes. The AD8044ARZ-14-REEL7 uses the standard 14-lead SOIC (R-14) footprint, matching AD8044AR-14-REEL7 and AD8044AR-14. It is functionally and pinout-identical to the non-Pb-free AD8044AR-14-REEL7 variant; the "Z" suffix denotes Pb-free terminations only. No PCB redesign is needed when migrating between AD8044ARZ-14-REEL7 and AD8044AR-14-REEL7 in existing SOIC-14 layouts.
