Product details
Overview
OPA354AIDBVTG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for high-speed video and precision analog signal conditioning. It delivers 250-MHz unity-gain bandwidth, 150 V/µs slew rate, 6.5 nV/√Hz input voltage noise, ±100 mA output drive, and operates from 2.5 V to 5.5 V supply. It is used in RGB video line drivers, photodiode transimpedance amplifiers, and ADC/DAC interface circuits.
For engineers reviewing the OPA354AIDBVTG4 datasheet, OPA354AIDBVTG4 pinout, OPA354AIDBVTG4 application, or OPA354AIDBVTG4 equivalent, key selection criteria include its 100-mA continuous output current capability, 0.02% differential gain error for NTSC video, 40-MHz 0.1-dB gain flatness, thermal shutdown protection at 160°C, and operation across –40°C to +125°C.
Technical Context
The OPA354AIDBVTG4 employs a complementary rail-to-rail input stage (N- and P-channel parallel pairs) enabling common-mode input range extending 100 mV beyond both supply rails. Its class AB output stage supports rail-to-rail swing within 100 mV of rails under 1-kΩ load and sustains ±100 mA continuous output current.
This op amp is unity-gain stable with 100-MHz gain-bandwidth product and features on-chip thermal shutdown (trip at 160°C, reset at 140°C), low 3-pA typical input bias current, and 4.9-mA quiescent current per channel - all specified over the full –40°C to +125°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250 MHz - enables stable operation as voltage follower in high-frequency signal paths without phase margin loss. |
| Slew Rate | 150 V/µs - supports clean 2-V step response in ≤11 ns, critical for fast-settling ADC input buffers. |
| Input Voltage Noise | 6.5 nV/√Hz at 1 MHz - preserves SNR in low-level sensor interfaces like photodiode transimpedance amps. |
| Output Current | ±100 mA continuous - drives 75-Ω back-terminated video cables or laser diodes without external boost. |
| Supply Range | 2.5 V to 5.5 V - compatible with single-supply 3.3-V and 5-V systems, including portable and industrial embedded designs. |
| Differential Gain/Phase | 0.02% / 0.09° (NTSC, RL = 150 Ω) - meets broadcast-grade video fidelity requirements without external compensation. |
| Quiescent Current | 4.9 mA per channel - balances speed and power efficiency in battery-sensitive or thermally constrained applications. |
Pinout & Package
OPA354AIDBVTG4 is packaged in a 5-pin SOT-23 (DBV) with body size 2.90 mm × 1.60 mm. The PowerPAD™ thermal pad is not present in this variant - only the standard SOT-23 package is used.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal; capable of ±100 mA continuous drive into loads down to 10 Ω. |
| 2 | V− | Negative (lowest) supply rail connection; must be tied to ground or negative supply in dual-rail configurations. |
| 3 | +IN | Noninverting input; part of complementary input pair enabling rail-to-rail common-mode range. |
| 4 | −IN | Inverting input; accepts signals from −0.1 V to V+ + 0.1 V, supporting true single-supply signal acquisition. |
| 5 | V+ | Positive (highest) supply rail connection; supports operation up to 5.5 V with internal ESD protection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail I/O | Input common-mode extends 100 mV beyond supplies; output swings to within 100 mV of rails at 1-kΩ load - maximizes dynamic range in low-voltage systems. |
| Thermal Shutdown | Activates at 160°C junction temperature and resets at 140°C - prevents permanent damage during overload or poor PCB thermal design. |
| Low Input Bias Current | 3 pA typical - minimizes offset drift and leakage errors in high-impedance sensor front-ends (e.g., photodiodes, piezoelectrics). |
| Video-Optimized Performance | 0.02% differential gain / 0.09° differential phase and 40-MHz 0.1-dB gain flatness - eliminates color distortion in RGB and composite video routing. |
| High Output Drive | Delivers ±100 mA continuously - eliminates need for external buffer stages when driving 75-Ω cables or moderate-power laser diodes. |
Applications
| RGB Video Line Driver | Photodiode Transimpedance Amp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA355IDBVR | 200-MHz GBW, rail-to-rail output only (not input), 125 V/µs slew rate, higher 10-pA input bias current. | Limited to applications where input common-mode does not approach rails; unsuitable for true single-supply sensor front-ends. | Select when lower power (3.5 mA IQ) and reduced bandwidth suffice, and rail-to-rail input is not required. |
| LMH6629MA/NOPB | 1.5-GHz GBW, 950 V/µs slew rate, 2.1 nV/√Hz noise, but only 60 mA output drive and no rail-to-rail input. | Better for ultra-wideband RF/IF signal chains; incompatible with rail-to-rail input or high-current video drive needs. | Choose for GHz-range small-signal amplification where noise and speed dominate over output drive and input range. |
Compared with OPA354AIDBVTG4, OPA355IDBVR trades bandwidth and input range for lower quiescent current, while LMH6629MA/NOPB offers extreme speed and noise performance at the cost of output drive and input flexibility - making OPA354AIDBVTG4 uniquely balanced for video, transimpedance, and mixed-signal interface roles.

FAQ
What is the maximum continuous output current specification for OPA354AIDBVTG4?
The OPA354AIDBVTG4 is rated for ±100 mA continuous output current per channel at VS = 5 V, as confirmed in Section 7.7 of the SBOS233G datasheet. This rating applies under recommended operating conditions and accounts for thermal limits - exceeding it risks triggering thermal shutdown at 160°C junction temperature. The device also supports peak currents up to 200 mA for short durations.
Does OPA354AIDBVTG4 support true rail-to-rail input operation?
Yes, OPA354AIDBVTG4 supports rail-to-rail input with a common-mode voltage range from (V−) −0.1 V to (V+) + 0.1 V, verified in Section 7.7 (VCM parameter). This is achieved via a complementary N/P-channel input stage, enabling use in single-supply systems where input signals swing near ground or V+ - unlike many high-speed op amps limited to mid-supply input ranges.
What package type is used for OPA354AIDBVTG4, and does it include PowerPAD™?
OPA354AIDBVTG4 uses the 5-pin SOT-23 (DBV) package with nominal dimensions 2.90 mm × 1.60 mm. Per TI's device information table and mechanical drawings, this variant does not incorporate the PowerPAD™ thermal enhancement - that feature is exclusive to the 8-pin HSOP (DDA) version of OPA354. Thermal resistance RθJA is 216.3°C/W for the DBV package.
Can OPA354AIDBVTG4 drive a 75-Ω video cable directly?
Yes, OPA354AIDBVTG4 is explicitly characterized for 75-Ω video applications, delivering 0.02% differential gain and 0.09° differential phase error with NTSC signals (Section 1, Features and Figure 18). When back-terminated per TI's Figure 32 reference design, it presents a purely resistive 150-Ω load - avoiding capacitive loading issues and preserving signal integrity up to 40 MHz.
What is the operating temperature range for OPA354AIDBVTG4?
OPA354AIDBVTG4 is fully specified over the extended industrial temperature range of –40°C to +125°C, as stated in Section 7.3 (Recommended Operating Conditions) and Section 10 (Thermal Range). All key parameters - including offset voltage, CMRR, PSRR, bandwidth, and output drive - are guaranteed across this range, making it suitable for under-hood automotive, industrial control, and outdoor equipment designs.
