Product details
Overview
ADA4850-1YCPZ-RL7 from Analog Devices is a single-channel, rail-to-rail output voltage-feedback operational amplifier optimized for high-speed, low-power video and portable signal conditioning applications. It delivers 175 MHz −3 dB bandwidth, 220 V/µs slew rate, 85 ns settling to 0.1%, 0.12% differential gain, and ultralow 150 nA power-down current - enabling battery-powered video cameras and digital still cameras with minimal power overhead.
For engineers reviewing the ADA4850-1YCPZ-RL7 datasheet, ADA4850-1YCPZ-RL7 pinout, ADA4850-1YCPZ-RL7 application, or ADA4850-1YCPZ-RL7 equivalent, key selection criteria include its 8-lead LFCSP package, rail-to-rail output swing within 80 mV of rails, −40°C to +125°C operation, and dual-supply compatibility down to ±2.5 V - critical for compact, thermally constrained, and wide-temperature embedded systems.
Technical Context
The ADA4850-1YCPZ-RL7 employs a true single-supply input stage supporting common-mode voltages from −0.2 V to +2.8 V (at +5 V supply) and a rail-to-rail output stage delivering 0.07 V to 4.92 V swing into 1 kΩ. Its voltage-feedback architecture enables stable unity-gain operation with 175 MHz bandwidth and 220 V/µs slew rate, while maintaining <0.2% differential gain/phase error at NTSC frequencies.
Power-down functionality is implemented via a dedicated PD pin requiring <0.7 V to disable (reducing quiescent current to ≤150 nA) and >0.8 V to enable, with 50 ns turn-on and 0.7 µs turn-off times. The device operates across 2.7 V to 6 V single supply or ±2.5 V bipolar supplies, with thermal resistance θJA = 80°C/W in its 3 mm × 3 mm LFCSP package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4891-1ARJZ-R7 | Lower bandwidth (220 MHz), higher quiescent current (5.5 mA), no power-down pin. | Better suited for fixed-power, high-bandwidth signal routing where ultra-low sleep current is unnecessary. | Select when maximum speed is prioritized over battery life and power gating is not required. |
| OPA355UA | Similar bandwidth (200 MHz), higher power-down current (1 µA), SO-8 package (larger footprint). | Preferred for legacy PCB designs using SOIC footprints and less stringent power-down leakage requirements. | Choose when board space allows SO-8 and 1 µA power-down current is acceptable for system sleep states. |
Compared with ADA4850-1YCPZ-RL7, ADA4891-1ARJZ-R7 trades 45 MHz extra bandwidth for 3.1 mA higher active current and no power-down control, while OPA355UA offers comparable speed in a larger package with 6.7× higher power-down leakage - making ADA4850-1YCPZ-RL7 optimal for space-constrained, battery-sensitive video endpoints.

FAQ
What is the operating temperature range for the ADA4850-1YCPZ-RL7?
The ADA4850-1YCPZ-RL7 is rated for continuous operation from −40°C to +125°C, qualified per AEC-Q100 stress test standards for automotive and industrial environments. This extended range ensures reliable performance in outdoor video cameras, under-hood sensors, and industrial vision systems where ambient temperatures exceed commercial limits. The ADA4850-1YCPZ-RL7 maintains specified bandwidth, slew rate, and distortion performance across this full range.
Does the ADA4850-1YCPZ-RL7 support bipolar supply operation?
Yes, the ADA4850-1YCPZ-RL7 supports bipolar supplies up to ±2.5 V. When operated on split rails, the power-down pin voltage must remain within 6 V of −VS to avoid damage - e.g., with ±2.5 V supplies, PD must not exceed +1 V. The ADA4850-1YCPZ-RL7 retains rail-to-rail output swing, 175 MHz bandwidth, and 150 nA power-down current under bipolar conditions, enabling use in legacy instrumentation and test equipment.
How does the power-down feature of the ADA4850-1YCPZ-RL7 work?
The ADA4850-1YCPZ-RL7 uses Pin 1 (PD) as an active-low enable: pulling PD <0.7 V disables the amplifier, reducing quiescent current to ≤150 nA; applying >0.8 V enables normal operation. Turn-on time is 50 ns, turn-off time is 0.7 µs. The ADA4850-1YCPZ-RL7 requires no external pull-up/down resistors but must never be left floating to prevent erratic behavior or increased leakage.
What is the output voltage swing capability of the ADA4850-1YCPZ-RL7 at 5 V supply?
At +5 V single supply, the ADA4850-1YCPZ-RL7 delivers an output voltage swing of 0.07 V to 4.92 V into 1 kΩ (i.e., within 70 mV of −VS and 80 mV of +VS). Under heavier 150 Ω load, swing degrades to 0.14 V to 4.83 V. This rail-to-rail performance maximizes usable dynamic range in 3.3 V and 5 V video signal paths without requiring level-shifting circuitry.
Can the ADA4850-1YCPZ-RL7 drive 75 Ω video loads directly?
The ADA4850-1YCPZ-RL7 is characterized for 150 Ω loads (standard for video drivers), delivering 0.12% differential gain and 0.09° differential phase at NTSC frequencies. While it can drive 75 Ω loads, output swing compresses to ~0.2 V to 4.7 V and distortion increases slightly. For robust 75 Ω video line driving, a series 75 Ω resistor is recommended to match impedance and maintain ADA4850-1YCPZ-RL7's specified video performance.
