Product details
Overview
OPA360AIDCKTG4 from Texas Instruments is a 3V single-supply, 6dB-gain, 2-pole video reconstruction amplifier with integrated sag correction and internal level shifter, optimized for DC- or AC-coupled portable video outputs in digital cameras and camera phones. It delivers rail-to-rail output swing (25mV above GND, 300mV below V+), operates from 2.7V to 3.3V, draws 6mA quiescent current, and features shutdown mode (<5µA).
For engineers reviewing the OPA360AIDCKTG4 datasheet, OPA360AIDCKTG4 pinout, OPA360AIDCKTG4 application, or OPA360AIDCKTG4 equivalent, key selection criteria include its integrated 9MHz Sallen-Key filter, sync-tip–preserving level shift (~60mV), differential gain/phase error (0.5%/1°), and SC70-6 footprint compatibility with space-constrained 3V video signal chains.
Technical Context
The OPA360AIDCKTG4 implements a fixed-gain (G = 2, +6dB) architecture with an internal 2-pole Sallen-Key reconstruction filter (9MHz cutoff) tailored for 27MHz-sampled DAC outputs. Its input common-mode range includes ground, enabling direct DC coupling to video DACs such as TI's DM320/DM270.
Internal level shifting prevents sync-pulse clipping by offsetting the output ~60mV above GND, while sag correction uses dual external capacitors (e.g., 22µF + 47µF) to replace bulky 220µF coupling caps without field tilt. Shutdown control reduces IQ to <5µA 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 use with 3V battery-powered systems without LDO overhead. |
| Small-Signal Bandwidth | 80MHz - supports full NTSC/PAL baseband video (0–5.5MHz) with margin for harmonics and filtering. |
| Output Swing (vs GND) | 25mV above GND, 300mV below V+ at 150Ω - ensures full sync-tip preservation and black-level fidelity. |
| Differential Gain/Phase | 0.5% / 1° at 150Ω - meets broadcast-grade video fidelity requirements for consumer imaging. |
| Quiescent Current | 6mA enabled, <5µA in shutdown - extends battery life in intermittent-use camera modules. |
| Filter Cutoff | 9MHz (2-pole Sallen-Key) - attenuates 27MHz DAC sampling aliases by −21dB while preserving passband flatness. |
| Enable Threshold | Logic HIGH ≥1.6V, LOW ≤0.8V - compatible with 1.8V/3.3V GPIO without level-shifting circuitry. |
Pinout & Package
OPA360AIDCKTG4 is housed in a 2.0mm × 2.1mm SC70-6 package with gull-wing leads, RoHS-compliant, MSL Level-2, and marked "AUW".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive supply rail | Accepts 2.7V–3.3V; requires 100nF ceramic bypass to GND for stability. |
| 2 (Enable) | Shutdown control input | Active-HIGH logic; internal pull-up enables device if left floating. |
| 3 (Out) | Amplified video output | Rail-to-rail capable; connects to SAG pin for sag-correction configuration. |
| 4 (+In) | Non-inverting input | DC-coupled input node; common-mode range includes GND for direct DAC interface. |
| 5 (GND) | Analog ground reference | Reference for Enable threshold, level-shift offset, and output swing metrics. |
| 6 (SAG) | Sag correction feedback terminal | Connects externally to OUT to configure dual-capacitor sag compensation network. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 2-pole reconstruction filter | 9MHz cutoff Sallen-Key topology eliminates need for external RC filter components and reduces board area. |
| DC-coupled output capability | Internal level shifter offsets output ~60mV above GND, preventing sync-tip clipping without output capacitors. |
| Sag correction architecture | Enables use of 22µF/47µF capacitor pair instead of 220µF, reducing BOM cost and PCB footprint by >70%. |
| Fixed 6dB gain (G = 2) | On-die precision resistors eliminate external gain-setting components and improve thermal drift performance. |
| Low-power shutdown mode | Reduces quiescent current to <5µA, extending battery runtime during video standby or preview modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA358 | Same SC70-6 package, 80MHz GBW, but no integrated filter or sag correction; G = 1 only. | Lacks reconstruction filtering and level shift - requires external components for sync-tip preservation. | Select OPA358 only when discrete filter design and layout control are preferred over integration. |
| OPA361 | G = 5.2V/V (14.3dB), 2.5V–3.3V supply, includes filter but no sag correction or level shift. | Higher gain suits low-output DACs; lacks DC-coupled output capability and sag-correction flexibility. | Choose OPA361 when system gain budget demands >6dB and sag correction is not required. |
Compared with OPA358 and OPA361, the OPA360AIDCKTG4 uniquely integrates all three functions-6dB gain, 2-pole filter, and sag correction-in one SC70-6 device, minimizing external passive count and ensuring broadcast-compliant video fidelity without design iteration.

FAQ
What is the function of the SAG pin on the OPA360AIDCKTG4?
The SAG pin on the OPA360AIDCKTG4 provides feedback for the sag correction circuit. When connected directly to the OUT pin, it enables the internal compensation network that allows use of smaller output coupling capacitors (e.g., 22µF + 47µF) without field tilt. This configuration replaces traditional 220µF capacitors and maintains video signal integrity across 50Hz–100Hz critical frequencies.
Does the OPA360AIDCKTG4 support true DC-coupled video output?
Yes, the OPA360AIDCKTG4 supports true DC-coupled output via its integrated level shifter, which offsets the output ~60mV above GND. This prevents sync-pulse clipping even with 0V input tip levels, allowing direct connection to 75Ω video loads without blocking capacitors-verified across −40°C to +85°C and with 150Ω/75Ω terminations.
What is the maximum operating supply voltage for the OPA360AIDCKTG4?
The absolute maximum supply voltage for the OPA360AIDCKTG4 is +3.6V, but its specified operating range is 2.7V to 3.3V. Operation above 3.3V may degrade video performance parameters such as differential gain error and output swing, and is not guaranteed per the datasheet's electrical characteristics table.
How does the OPA360AIDCKTG4 achieve 0.5% differential gain error?
The OPA360AIDCKTG4 achieves 0.5% differential gain error through precision internal resistor matching in its fixed G = 2 gain stage, combined with a tightly controlled 2-pole Sallen-Key filter (9MHz cutoff) that maintains amplitude flatness across the 4.5MHz video baseband. This performance is measured at RL = 150Ω and confirmed over temperature per TI SB0S294E.
Is the OPA360AIDCKTG4 pin-compatible with other SC70-6 video amplifiers like OPA358?
No, the OPA360AIDCKTG4 is not pin-compatible with OPA358. While both use SC70-6 packages, their pinouts differ: OPA360AIDCKTG4 assigns Pin 6 to SAG, whereas OPA358 uses Pin 6 as NC or a different function. Substituting without layout revision will cause functional failure due to misrouted SAG and Enable connections.
