Product details
Overview
OPA362AIDCKT from Texas Instruments is a 3V video amplifier IC optimized for portable video applications, featuring internal gain of 5.2V/V, integrated two-pole reconstruction filter (f−3dB = 8.5 MHz), rail-to-rail output swing within 5 mV of GND and 250 mV from V+, and TV-detection support for automatic video start/stop in OMAP343x/DaVinci™-based camera phones.
For engineers reviewing the OPA362AIDCKT datasheet, OPA362AIDCKT pinout, OPA362AIDCKT application, or OPA362AIDCKT equivalent, this device delivers verified differential gain error (1.2%), differential phase error (1.6°), 65 dB SNR, shutdown current <1.5 μA, and SC70-6 package compatibility with 2.5V–3.3V single-supply operation - critical for space-constrained, battery-sensitive video signal chains.
Technical Context
The OPA362AIDCKT implements a Sallen-Key two-pole filter with 8.5 MHz cutoff to reconstruct DAC output signals while suppressing 54 MHz sampling aliases by −25 dB. Its input common-mode range extends to GND (0 V) on 2.5V–3.3V supplies, enabling DC-coupled connection to video-DACs with 0.4–0.55 VPP output.
An integrated level-shift circuit offsets the output by ~11 mV (typical) to prevent sync-pulse clipping at 0 V input, and the Enable pin supports 1.8 V CMOS logic thresholds (0.5 V low, 1.3 V high) with 1.5 μs turn-on and 50 ns turn-off timing - essential for low-latency TV-detect functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 3.3 V - enables direct integration with OMAP343x/DaVinci™ processor auxiliary rails without level-shifting. |
| Small-Signal Bandwidth | 8.5 MHz - matches NTSC/PAL video bandwidth requirements and suppresses DAC sampling artifacts. |
| Gain Accuracy | 5.06–5.28 V/V (±2.2%) - stable over temperature due to matched 872 Ω RIN and 3750 Ω RSET resistors. |
| Differential Gain/Phase | 1.2% / 1.6° - meets broadcast-grade video fidelity standards for color bar and multiburst test patterns. |
| Output Swing | Within 5 mV of GND and 250 mV of V+ into 150 Ω - supports DC-coupled back-terminated video loads without AC coupling capacitors. |
| Quiescent Current | 4.3 mA (enabled), 1.5 μA (shutdown) - extends battery life in intermittent-use camera phone video output paths. |
| Operating Temperature | −40°C to +125°C - qualified for automotive infotainment and industrial portable display environments. |
Pinout & Package
OPA362AIDCKT is housed in a RoHS-compliant SC70-6 package (2.0 mm × 2.1 mm, 1.1 mm max height), with pin 1 located at the index area corner per JEDEC MO-203 AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts 2.5 V–3.3 V single supply; requires 100 nF ceramic bypass capacitor to GND. |
| Enable | Shutdown control input | CMOS-compatible logic input (0.5 V low, 1.3 V high); disconnects internal feedback during disable to support TV-detect. |
| Out | Amplified video output | Rail-to-rail output driving 75 Ω or 150 Ω video loads; includes internal level shift to preserve sync-tip integrity. |
| +In | Non-inverting input | DC-coupled input accepting 0 V to 0.55 V common-mode range; connects directly to video-DAC output. |
| GND | Ground reference | System ground return for supply, input, and output; referenced for Enable logic and internal level-shift circuit. |
| RSET | Internal gain-setting node | Internally connected to 3750 Ω resistor; not user-accessible - sets fixed 5.2 V/V gain with 872 Ω RIN. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated two-pole filter | 8.5 MHz cutoff Sallen-Key topology eliminates external RC components and ensures flat group delay (26 ns variation) across video band. |
| DC-coupled I/O architecture | Input range includes GND and output swings to within 5 mV of GND - removes need for AC-coupling capacitors and associated board area. |
| TV-detection interface | Enables automatic video enable/disable via GPIO monitoring of OPA362AIDCKT output voltage drop when 75 Ω load is connected. |
| Low-power shutdown mode | Reduces quiescent current to 1.5 μA while maintaining pin states - critical for standby power budgeting in mobile devices. |
| Internal precision resistor matching | 872 Ω RIN and 3750 Ω RSET track within 0.5% over temperature - guarantees stable 5.2 V/V gain without external trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA361AIDCKT | Same SC70-6 package, but G = 2 V/V, no TV-detect, no internal RSET/RIN - requires external gain resistors and separate detection circuitry. | Lacks integrated TV-detect and fixed-gain architecture - suitable only where programmable gain or non-OMAP343x platforms are used. | Select OPA361AIDCKT only if gain flexibility or absence of TV-detect logic is required; otherwise OPA362AIDCKT provides superior system integration. |
| OPA358AIDBVR | SOT23-6 package (2.9 mm × 1.6 mm), 70 MHz bandwidth, 6 mA IQ, 5 μA shutdown - higher bandwidth but larger footprint and no integrated filter or TV-detect. | Requires external 2-pole filter components and discrete TV-detect implementation - increases BOM count and layout complexity. | Choose OPA358AIDBVR only when >70 MHz bandwidth is mandatory; OPA362AIDCKT offers better size/power/video-fidelity tradeoff for standard-definition video. |
Compared with OPA361AIDCKT and OPA358AIDBVR, the OPA362AIDCKT uniquely integrates gain-setting resistors, a matched two-pole filter, and TV-detect logic in the smallest SC70-6 footprint - reducing total solution size by 40% and eliminating 7 external passive components required by alternatives.

FAQ
What is the exact gain configuration of the OPA362AIDCKT?
The OPA362AIDCKT features a fixed internal gain of 5.2 V/V, achieved through laser-trimmed, temperature-matched 872 Ω input resistor (RIN) and 3750 Ω set resistor (RSET). This ratio is guaranteed from −40°C to +125°C with ±0.5% matching, eliminating need for external gain-setting components. The OPA362AIDCKT does not support user-adjustable gain.
Does the OPA362AIDCKT require external filter components?
No, the OPA362AIDCKT integrates a complete two-pole Sallen-Key reconstruction filter with 8.5 MHz cutoff frequency. All filter components - including the 872 Ω RIN, 3750 Ω RSET, and internal capacitors - are monolithically embedded. No external RC network is needed, unlike discrete op amp solutions such as OPA358AIDBVR.
How does the TV-detect function work on the OPA362AIDCKT?
The OPA362AIDCKT supports TV-detect by briefly disabling its output via the Enable pin, allowing an external pull-up resistor (e.g., 10 kΩ to 1.8 V) to raise the Out pin voltage. When a 75 Ω video load is connected, the voltage drops significantly - detectable by a GPIO interrupt. This mechanism enables automatic video activation without manual user input in the OPA362AIDCKT.
What is the maximum output current capability of the OPA362AIDCKT?
The OPA362AIDCKT delivers ±80 mA output current into a 75 Ω load, sufficient to drive standard back-terminated CVBS video lines. At 150 Ω load, it maintains rail-to-rail swing with 130–250 mV headroom from V+ and 0.15–5 mV from GND. This current drive is verified across −40°C to +125°C and supports transient video sync pulses without clipping.
Is the OPA362AIDCKT compatible with 1.8 V logic-level control signals?
Yes, the Enable pin of the OPA362AIDCKT accepts 1.8 V CMOS logic levels: a valid logic high is ≥1.3 V, and a valid logic low is ≤0.5 V. This allows direct interfacing with OMAP343x GPIOs and TWL92230 energy management ICs without level-shifting circuitry - a key design advantage confirmed in TI Application Report SBOA109 for the OPA362AIDCKT.
