Product details
Overview
OPA360AIDCKRG4 from Texas Instruments is a 3V single-supply, 6dB-gain, rail-to-rail output video amplifier with integrated 2-pole reconstruction filter, sag correction, and internal level shifter-designed for DC-coupled or AC-coupled video signal conditioning in portable digital cameras and camera phones. It operates from 2.7V to 3.3V, delivers 80MHz bandwidth, achieves ±25mV negative rail output swing, and consumes only 6mA quiescent current.
For engineers reviewing the OPA360AIDCKRG4 datasheet, OPA360AIDCKRG4 pinout, OPA360AIDCKRG4 application, or OPA360AIDCKRG4 equivalent, key selection criteria include its integrated 9MHz Sallen-Key filter, 60mV internal level-shift voltage for sync-tip preservation, sag-correction support for sub-47µF coupling capacitors, and SC70-6 footprint compatibility with space-constrained mobile video interfaces.
Technical Context
The OPA360AIDCKRG4 implements a fixed-gain (G = 2, +6dB) architecture with an internal 2-pole Sallen-Key low-pass filter (fC ≈ 9MHz) optimized for DAC reconstruction in 27MHz-sampled video signals-delivering −21dB attenuation at 27MHz to suppress sampling aliases. Its input common-mode range includes ground, enabling direct DC coupling from current-output video DACs (e.g., TI DM270/DM320), while the internal level shifter offsets the output by ~60mV to prevent sync-pulse clipping at 0V input.
It supports dual output configurations: DC-coupled operation eliminates output capacitors entirely, while AC-coupled mode leverages sag correction with 22µF/47µF capacitor pairs to replace traditional 220µF designs. Shutdown functionality reduces current to <5µA via logic-controlled Enable pin (VIL ≤ 0.8V, VIH ≥ 1.6V), with 1.5µs enable time and 50ns disable time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V to 3.3V single supply-enables direct integration with 3V video processors without level-shifting circuitry. |
| Small-Signal Bandwidth | 80MHz-supports full NTSC/PAL baseband video fidelity up to 5.5MHz with margin. |
| Gain Accuracy | +6dB ±0.2dB (5.8–6.2dB)-ensures precise luminance/chrominance amplitude matching across temperature. |
| Differential Gain/Phase Error | 0.5% / 1° at 150Ω load-meets broadcast-grade video linearity requirements for color fidelity. |
| Output Swing (vs GND) | 25mV minimum negative swing, 300mV positive swing-enables full sync-tip preservation and black-level integrity. |
| Quiescent Current | 6mA typical (9mA max over temp)-balances performance and battery life in always-on video paths. |
| Shutdown Current | ≤5µA-reduces system standby power by >1000×, critical for intermittent video output in DSCs. |
Pinout & Package
OPA360AIDCKRG4 is housed in a 2.0mm × 2.1mm SC70-6 package with JEDEC-standard pinout and moisture sensitivity level MSL-2-260°C-1 year. The package supports high-density placement in compact camera modules and mobile PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Enable) | Logic control input | Active-HIGH enable: ≥1.6V enables amplifier; ≤0.8V disables output and reduces IQ to <5µA. |
| 2 (+In) | Non-inverting input | DC-coupled input node accepting ground-referenced video signals from DACs. |
| 3 (Out) | Amplified output | Rail-to-rail output driving 75Ω or 150Ω video loads; connects to SAG pin for sag correction. |
| 4 (GND) | Analog ground reference | Common return for input, output, and enable logic; must be low-impedance for video SNR. |
| 5 (V+) | Positive supply rail | Accepts 2.7V–3.3V; requires local 100nF ceramic bypass to GND per datasheet layout guidance. |
| 6 (SAG) | Sag correction feedback node | Connected externally to OUT to configure active sag compensation network with 22µF/47µF caps. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 2-pole reconstruction filter | 9MHz Sallen-Key topology providing −21dB attenuation at 27MHz to eliminate DAC sampling aliases without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA357 | Higher GBW (150MHz), RRIO, but no integrated filter or sag correction; requires external gain resistors and reconstruction filter. | Used where wider bandwidth or rail-to-rail input is needed, but adds design complexity and board area for filtering. | Select OPA357 only if >80MHz bandwidth or dual-supply flexibility is required-OPA360AIDCKRG4 provides lower-risk, smaller-footprint video path. |
| OPA361 | Same SC70-6 package and sag correction, but fixed G = 5.2V/V (14.3dB); narrower 30MHz bandwidth; optimized for 2.5V–3.3V. | Targeted at higher-gain, lower-frequency video paths (e.g., VGA scaling), not standard CVBS reconstruction. | Choose OPA361 only for applications needing >6dB gain and tolerance for reduced alias rejection-OPA360AIDCKRG4 remains optimal for 6dB/80MHz DAC filtering. |
Compared with OPA357 and OPA361, the OPA360AIDCKRG4 uniquely combines 6dB gain, 80MHz bandwidth, integrated 2-pole filter, and sag correction in SC70-6-making it the only drop-in solution for space-constrained, 3V portable video DAC interface without external passive filtering.

FAQ
What is the primary function of the SAG pin on the OPA360AIDCKRG4?
The SAG pin on the OPA360AIDCKRG4 is a dedicated feedback terminal used to configure the internal sag correction circuit. When connected to the OUT pin, it enables active compensation that reduces required output coupling capacitance-allowing use of 22µF/47µF capacitors instead of traditional 220µF designs. This configuration preserves video field tilt performance while minimizing board area and cost. The OPA360AIDCKRG4 datasheet specifies exact capacitor values and layout guidelines for optimal sag correction.
Does the OPA360AIDCKRG4 support true DC-coupled output operation?
Yes, the OPA360AIDCKRG4 supports true DC-coupled output operation due to its internal level shifter, which offsets the output by ~60mV to prevent sync-pulse clipping when the input reaches 0V. This allows direct connection to 75Ω video loads without output coupling capacitors-eliminating capacitor-induced drift, size, and cost. In DC-coupled mode, the OPA360AIDCKRG4 maintains full video fidelity and operates safely down to 2.5V supply, as verified in TI's Figure 15 and Figure 16 test circuits.
What is the cutoff frequency and topology of the integrated 2-pole filter in the OPA360AIDCKRG4?
The OPA360AIDCKRG4 integrates a 2-pole Sallen-Key low-pass filter with a nominal cutoff frequency of 9MHz. This topology is explicitly designed for DAC reconstruction in 27MHz-sampled video systems-providing −21dB attenuation at 27MHz to suppress sampling aliases while maintaining flat passband response up to 4.5MHz (±0.4dB). Filter performance is validated in TI's Figure 3–Figure 5 multiburst and multipulse test waveforms, confirming no visible distortion across the NTSC/PAL baseband.
How does the OPA360AIDCKRG4 handle input signals referenced to ground?
The OPA360AIDCKRG4 features a ground-inclusive input common-mode range (GND to V+ − 1.5V), enabling direct DC coupling from current-output video DACs such as those in TI's DM270/DM320 processors. Its input bias current is ultra-low (±3pA), minimizing voltage error across typical DAC termination resistors (e.g., 200Ω). This architecture eliminates level-shifting circuitry and ensures accurate signal transfer without degradation of differential gain (0.5%) or phase (1°) metrics.
What are the absolute maximum ratings for supply voltage and operating temperature of the OPA360AIDCKRG4?
The OPA360AIDCKRG4 has an absolute maximum supply voltage of +3.6V (V+ to V−) and an operating temperature range of −40°C to +85°C. These limits are strictly defined in the TI SB0S294E datasheet Absolute Maximum Ratings table. Exceeding +3.6V risks permanent damage, while operation outside −40°C to +85°C may cause parametric shift or functional failure. The device is qualified for industrial temperature operation and shipped in MSL-2-260°C-1 year packaging compatible with standard reflow profiles.
