Product details
Overview
OPA358AIDCKT from Texas Instruments is a single-channel, 80MHz high-speed rail-to-rail output operational amplifier optimized for 3V single-supply video signal conditioning. It delivers 0.5dB gain flatness to 25MHz, differential gain of 0.3%, and differential phase of 0.7°, with rail-to-rail output swing (within 5mV of GND under 150Ω load) and shutdown current <5µA - enabling low-power portable video applications including digital still cameras and camera phones.
For engineers reviewing the OPA358AIDCKT datasheet, OPA358AIDCKT pinout, OPA358AIDCKT application, or OPA358AIDCKT equivalent, key selection criteria include its SC70-6 package footprint, 2.7V–3.3V supply range, 55V/µs slew rate, enable-controlled power gating, and verified PAL/NTSC video performance metrics - all critical for compact, battery-powered imaging front-ends.
Technical Context
The OPA358AIDCKT employs a CMOS input stage with rail-to-rail output using a class AB common-source architecture, supporting input common-mode range from (V−) − 0.1V to (V+) − 1.0V and output swing to within 100mV of V− and 200mV of V+ (at 150Ω to VS/2). Its internal enable logic accepts TTL-compatible thresholds (≤0.8V LOW, ≥1.6V HIGH), with 1.5µs enable time and 50ns disable time, allowing fast multiplexing in shared video bus architectures.
Designed specifically for 3V video buffering and filtering, it achieves stable operation driving 75Ω video loads and capacitive loads up to several hundred pF - aided by optional series output resistance (10–20Ω) for unity-gain configurations. Its transimpedance capability is validated for photodiode amplification with ≤1.5pF input capacitance and GBW-limited bandwidth scaling per RF·CD design rules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 80MHz gain-bandwidth product ensures stable gain ≥2 up to 25MHz - sufficient for full NTSC/PAL baseband (0–5.5MHz) with margin. |
| Slew Rate | 55V/µs supports 100mVPP video signals at 25MHz without distortion - critical for multiburst and multipulse test compliance. |
| Output Swing | Rail-to-rail: within 5mV of GND (150Ω to GND); within 100mV of V− and 200mV of V+ (150Ω to VS/2) - enables DC-coupled sync pulse handling. |
| Video Performance | 0.3% differential gain / 0.7° differential phase error at PAL standard - meets broadcast-grade color fidelity requirements. |
| Supply Range | +2.7V to +3.3V specified; operates down to +2.5V - compatible with Li-ion/Li-poly battery discharge profiles in portable devices. |
| Shutdown Current | <5µA enables >1000× quiescent current reduction vs active mode (5.2mA) - extends battery life during idle video capture states. |
| Input Range | Includes ground (V− −0.1V) and extends to within 1V of V+ - supports single-supply DC-coupled sensor interfaces and sync-level inputs. |
Pinout & Package
OPA358AIDCKT is housed in a 6-pin SC70-6 (DCK) package - measuring 2.0mm × 1.25mm × 0.95mm - optimized for space-constrained video modules and mobile camera PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Enable) | Digital control input | Active-HIGH TTL-compatible enable: ≥1.6V enables amplifier; ≤0.8V disables output and reduces IQ to <5µA; internally pulled up if floating. |
| 2 (V+) | Positive supply | Accepts +2.5V to +3.6V; bypass with 100nF ceramic capacitor near pin for stability in video-frequency operation. |
| 3 (+In) | Non-inverting input | CMOS input with ±0.3pA bias current; common-mode range extends to ground - supports DC-coupled sensor inputs. |
| 4 (GND) | Ground reference | System ground return for supply, enable logic, and input/output signals - must be low-impedance for video SNR. |
| 5 (−In) | Inverting input | Differential input node; used with feedback network to set gain (e.g., G=2 via 1kΩ/1kΩ resistors in Figure 1). |
| 6 (Out) | Amplified output | Rail-to-rail output capable of driving 75Ω video loads; enters high-Z state when disabled - enables wired-OR multiplexing. |
Key Features
| Feature | Design Value |
|---|---|
| SC70-6 footprint | Smallest standardized package for video op amps (2.0mm × 1.25mm), reducing board area by >50% vs SOT-23-6 in camera module layouts. |
| Sag correction support | Enables use of 22µF–47µF AC-coupling caps instead of 220µF - eliminates field tilt while cutting BOM cost and height in set-top-box filters. |
| DC-coupled output capability | Swings to within 5mV of GND with 150Ω load - allows removal of output coupling caps in portable DSCs, saving space and avoiding cap-induced droop. |
| Fast enable/disable timing | 1.5µs enable / 50ns disable - permits sub-microsecond video channel switching in multi-sensor camera phones without visible glitches. |
| Low-noise CMOS input | 6.4nV/√Hz input voltage noise at 1MHz and ≤1.5pF input capacitance - preserves SNR in transimpedance photodiode amplifiers. |
Applications
| Digital Still Cameras | Camera Phones |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA360AIDCKT | G = 2 fixed gain, integrated 2-pole filter, sag correction, same SC70-6 package and enable pin. | Optimized for plug-and-play video filtering; lacks user-configurable gain and bandwidth flexibility of OPA358AIDCKT. | Select OPA360AIDCKT when fixed-gain, filtered video path simplifies layout and reduces external components. |
| OPA357AIDCKT | 200MHz GBW, 120V/µs slew rate, same rail-to-rail I/O and SC70-6 package; higher quiescent current (8.5mA). | Better suited for higher-resolution video (e.g., 720p/1080p baseband) or faster transient response needs beyond PAL/NTSC. | Select OPA357AIDCKT when system requires >25MHz bandwidth headroom or improved settling time (<25ns to 0.1%). |
Compared with OPA358AIDCKT, OPA360AIDCKT trades configurability for integration in fixed-video-path designs, while OPA357AIDCKT provides bandwidth headroom at the cost of higher power - making OPA358AIDCKT the optimal balance for mainstream 3V portable video applications.

FAQ
What is the minimum supply voltage required for reliable operation of the OPA358AIDCKT?
The OPA358AIDCKT is fully specified from +2.7V to +3.3V, but functional operation is guaranteed down to +2.5V. At 2.5V, it maintains rail-to-rail output swing without clipping for typical video signals, though parameters like GBW and slew rate degrade slightly - confirmed in the Electrical Characteristics table and Typical Characteristics curves.
Can the OPA358AIDCKT drive a 75Ω video load directly?
Yes, the OPA358AIDCKT is characterized driving 150Ω loads to GND or VS/2, and its output stage delivers ±50mA into 0.5V from rails - sufficient for 75Ω loads with 1VPP signals. Application Figure 1 shows a standard 75Ω termination, and the Output Voltage vs Output Current curve confirms stable swing at 75Ω across temperature.
Does the OPA358AIDCKT require external compensation for unity-gain stability?
No external compensation is required for unity-gain stability with resistive loads. However, for capacitive loads >100pF in unity-gain configuration, a 10Ω–20Ω series resistor at the output (per Figure 10) is recommended to maintain phase margin and prevent ringing - a proven method validated in the Capacitive Load and Stability section.
How does the enable pin behave if left unconnected on the OPA358AIDCKT?
If the enable pin is left unconnected, internal pull-up circuitry activates the amplifier by default. The OPA358AIDCKT will operate normally with full 5.2mA quiescent current and full video performance - no external pull-up is needed unless active-low control logic is implemented elsewhere in the system.
Is the OPA358AIDCKT suitable for transimpedance amplifier applications with photodiodes?
Yes, the OPA358AIDCKT is explicitly validated for wideband transimpedance amplification: its 80MHz GBW, ≤1.5pF input capacitance, 6.4nV/√Hz voltage noise, and low input bias current (±0.3pA typ) make it ideal for low-voltage single-supply photodiode interfaces - detailed in the Wideband Transimpedance Amplifier section with design equations.
