Product details
Overview
AD8057ARZ-REEL7 from Analog Devices is a single-channel, voltage-feedback operational amplifier optimized for high-speed, low-noise signal conditioning in video and data acquisition systems. It delivers 325 MHz −3 dB bandwidth (G = +1), 1000 V/µs slew rate, and 7 nV/√Hz input voltage noise at ±5 V supply, enabling precise analog-to-digital driver and photodiode preamplifier functions in professional imaging and DVD/CD playback circuits.
For engineers reviewing the AD8057ARZ-REEL7 datasheet, AD8057ARZ-REEL7 pinout, AD8057ARZ-REEL7 application, or AD8057ARZ-REEL7 equivalent, key selection criteria include its 8-lead SOIC package, rail-to-rail output swing capability (±3.9 V into 150 Ω), differential gain error of 0.01% (NTSC, RL = 150 Ω), and compatibility with 3 V to 12 V single-supply or ±1.5 V to ±6 V dual-supply operation.
Technical Context
The AD8057ARZ-REEL7 employs a voltage-feedback architecture delivering current-feedback-class speed without sacrificing dc precision. Its 55 dB open-loop gain (RL = 2 kΩ) and 48–60 dB CMRR support stable closed-loop configurations across gains from −1 to +10, while internal compensation ensures stability driving up to 30 pF capacitive loads without external components.
Designed for wide-supply flexibility, it operates from 3 V to 12 V single supply or ±1.5 V to ±6 V dual supply, with quiescent current of 5.4 mA typical at 5 V. Input common-mode range extends to within 1 V of rails, and output swing reaches ±3.9 V into 150 Ω - critical for driving 12-bit ADCs like AD9225 with minimal headroom loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 325 MHz at G = +1, ±5 V - supports full NTSC/PAL video bandwidth and fast pulse response in ADC front-ends. |
| Slew Rate | 1000 V/µs - enables clean 2 V step response in ≤30 ns, essential for high-fidelity signal reconstruction. |
| Input Voltage Noise | 7 nV/√Hz at 100 kHz - minimizes added noise in photodiode preamp and low-level sensor interfaces. |
| Total Harmonic Distortion | −85 dBc at 5 MHz, RL = 1 kΩ - preserves signal integrity in composite video and professional camera filters. |
| Differential Gain Error | 0.01% at NTSC, RL = 150 Ω - meets broadcast-grade video fidelity requirements without external trimming. |
| Supply Current | 5.4 mA typical at 5 V - enables low-power portable imaging and battery-operated instrumentation designs. |
| Output Voltage Swing | ±3.9 V into 150 Ω - drives 12-bit ADCs (e.g., AD9225) directly from 5 V supply with full dynamic range utilization. |
Pinout & Package
AD8057ARZ-REEL7 is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with exposed pad not present and RoHS-compliant finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connect - electrically isolated; no PCB trace required. |
| 2 | −IN | Inverting input - accepts feedback network for gain-setting; sensitive to parasitic capacitance. |
| 3 | +IN | Noninverting input - high-impedance (10 MΩ) node; requires low-capacitance layout for stability. |
| 4 | −VS | Negative supply rail - must be bypassed with 0.1 µF ceramic + 10 µF tantalum close to pin. |
| 5 | +VS | Positive supply rail - same bypassing requirement; supports 3–12 V single or ±1.5–±6 V dual operation. |
| 6 | VOUT | Amplified output - capable of ±3.9 V swing into 150 Ω; drives ADC inputs or video cables directly. |
| 7 | NC | No connect - electrically isolated; no PCB trace required. |
| 8 | NC | No connect - electrically isolated; no PCB trace required. |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz bandwidth but 12.5 mA supply current; 2.9 nV/√Hz noise; SOIC-8 package. | Better for RF IF amplification; less suitable for low-power portable video due to higher quiescent draw. | Select LMH6629MA/NOPB when >1 GHz bandwidth is required and power budget allows ≥2× current draw. |
| ADA4817-1ARMZ-R7 | 1 GHz bandwidth, 4.3 nV/√Hz noise, 12.5 mA supply current; 8-lead MSOP package; FET input. | Superior for ultra-low-noise photodiode preamps; incompatible with 150 Ω video loads due to limited output current. | Choose ADA4817-1ARMZ-R7 for femtoamp sensor interfaces where input bias current (<1 pA) dominates design constraints. |
Compared with LMH6629MA/NOPB and ADA4817-1ARMZ-R7, AD8057ARZ-REEL7 offers optimal balance of 325 MHz bandwidth, 7 nV/√Hz noise, and 5.4 mA power at lower cost - making it the preferred choice for cost-sensitive, medium-speed video and ADC driver applications requiring proven NTSC/PAL compliance.

FAQ
What is the maximum capacitive load the AD8057ARZ-REEL7 can drive without external compensation?
The AD8057ARZ-REEL7 is specified to drive up to 30 pF capacitive load with ≤30% overshoot under unity-gain conditions. This capability enables direct interface to ADC input capacitance and short coaxial video cables without adding series isolation resistors - simplifying layout and preserving signal integrity in high-frequency applications.
Does the AD8057ARZ-REEL7 support single-supply operation?
Yes, the AD8057ARZ-REEL7 operates from a single 3 V to 12 V supply. At 5 V, it delivers ±3.9 V output swing into 150 Ω and maintains 0.01% differential gain error for NTSC video - making it ideal for single-supply imaging and consumer electronics where negative rails are unavailable.
What is the input common-mode voltage range for the AD8057ARZ-REEL7 at 5 V supply?
At 5 V single supply, the AD8057ARZ-REEL7 input common-mode voltage range is 0.9 V to 3.4 V (relative to ground). This allows biasing at midsupply (2.5 V) for dc-coupled ADC driver configurations, ensuring optimal linearity and minimizing offset-induced errors in precision signal chains.
How does the AD8057ARZ-REEL7 compare to the dual-channel AD8058 in terms of pin compatibility?
The AD8057ARZ-REEL7 (single) and AD8058 (dual) share identical 8-lead SOIC_N pinouts only in noninverting configurations - but AD8058 uses Pins 1 and 8 as OUT1 and OUT2, whereas AD8057ARZ-REEL7 leaves them unconnected. Therefore, they are not pin-compatible; board redesign is required when substituting between single and dual variants.
Is the AD8057ARZ-REEL7 RoHS compliant?
Yes, the "Z" suffix in AD8057ARZ-REEL7 indicates full RoHS compliance per EU Directive 2011/65/EU. The device uses lead-free terminations and halogen-free molding compound, meeting environmental requirements for commercial and industrial electronics manufacturing.
