Product details
Overview
OPA832IDRG4 from Texas Instruments is a low-power, fixed-gain +2 voltage-feedback operational amplifier optimized for single-supply video line driving and CCD imaging channel buffering. It delivers 80MHz small-signal bandwidth (G = +2), 350V/µs slew rate, 9.3nV/√Hz input voltage noise, 4.9VPP output swing on +5V supply, and operates from +2.8V to +11V single supply or ±1.4V to ±5.5V dual supply.
For engineers reviewing the OPA832IDRG4 datasheet, OPA832IDRG4 pinout, OPA832IDRG4 application, or OPA832IDRG4 equivalent, this page provides verified circuit role, validated SOT23-5 pin mapping, confirmed NTSC differential gain/phase performance (0.11%/0.14°), real-world video load drive capability (up to 4 × 150Ω), and alternative selection guidance for low-power, fixed-gain video buffer applications.
Technical Context
The OPA832IDRG4 uses a voltage-feedback architecture with internal 400Ω RF/RG resistors enabling stable +2 gain without external components. Its complementary common-emitter output stage achieves rail-to-rail output swing - within 30mV of ground and 130mV of VS - while supporting input voltages extending below ground and to within 1.7V of VS.
It is internally compensated for unity-gain stability across resistive loads and features low distortion that improves with reduced signal swing. The device supports AC-coupled configurations with external DC bias networks (e.g., 887Ω/258Ω divider for +3.3V VCM = 0.75V) and includes design provisions for harmonic distortion reduction via optional supply decoupling (0.01µF between ±VS).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 92MHz at G = +2, +5V supply - enables high-fidelity baseband video and ultrasound signal amplification up to ~40MHz Nyquist. |
| Slew Rate | 348V/µs at +5V - supports clean 2VPP transient response with ≤4.6ns rise time for fast video sync pulses. |
| Input Voltage Noise | 9.3nV/√Hz - preserves dynamic range in CCD imaging channels and low-level analog front-ends. |
| Output Swing | 4.9VPP into 1kΩ on +5V supply - delivers full-scale video signal headroom with minimal clipping risk. |
| Quiescent Current | 3.9mA at +5V - enables portable consumer electronics and battery-powered ultrasound systems. |
| NTSC Differential Gain/Phase | 0.11% / 0.14° at RL = 150Ω - meets broadcast-grade video line driver requirements without external tuning. |
| Supply Range | +2.8V to +11V single supply - interoperable with 3.3V, 5V, and 10V system rails without level-shifting. |
Pinout & Package
SOT23-5 package (DBV), 5-pin ultra-small surface-mount, Pb-free, rated for −40°C to +85°C operation. Thermal resistance θJA = 150°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Output | Amplified signal output node | Drives 150Ω video loads directly; swing limited to 0.03V above ground and 4.94V below +5V at light load. |
| 2 - −VS | Negative supply connection | Required for dual-supply operation (±1.4V to ±5.5V); tied to ground in single-supply mode. |
| 3 - Noninverting Input | Positive input terminal | Accepts signals down to −0.5V (single-supply), enabling DC-coupled sensor interfaces like CCD outputs. |
| 4 - +VS | Positive supply connection | Supports +2.8V to +11V; supplies internal bias network and output stage; decoupling required. |
| 5 - Inverting Input | Negative input terminal | Internally connected to 400Ω feedback resistor; sets fixed +2 gain when noninverting input is biased at VCM. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed +2 gain with internal 400Ω RF/RG | Eliminates external gain-setting resistors, reducing BOM count and layout sensitivity in video line drivers. |
| Rail-to-rail output swing | Reaches within 30mV of ground and 130mV of +VS - maximizes signal fidelity in single-supply 5V video systems. |
| Input range includes ground | Accepts inputs as low as −0.5V on +5V supply - supports DC-coupled CCD, ultrasound transducer, and sensor outputs. |
| Low distortion improving with smaller swing | 2nd-harmonic −62dBc at 2VPP/5MHz drops to −74dBc at 1VPP - ideal for variable-amplitude medical imaging signals. |
| Optimized for NTSC video | 0.11% dG / 0.14° dP at 150Ω load - meets EIA-770.1 compliance without external peaking or compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA830IDBVR | Adjustable gain (−1, +1, +2) via external resistors; 200MHz GBW; higher 5.5mA IQ at +5V. | Requires external gain-setting resistors; better suited for multi-gain systems needing flexibility over fixed performance. | Select OPA830IDBVR only if programmable gain or wider bandwidth (>92MHz) is required; not drop-in compatible. |
| LMH6702MF/NOPB | Unity-gain stable; 1.7GHz GBW; 1000V/µs slew rate; 12.5mA IQ; SO-8 only. | Higher power, wider bandwidth, but no internal gain resistors - requires full external feedback network. | Choose LMH6702MF/NOPB for ultra-wideband applications (>100MHz) where OPA832IDRG4's fixed +2 gain is insufficient. |
Compared with OPA832IDRG4, OPA830IDBVR offers gain flexibility at higher power, while LMH6702MF/NOPB delivers extreme bandwidth at significantly increased quiescent current and layout complexity - making OPA832IDRG4 optimal for cost- and power-constrained fixed-gain video and imaging paths.

FAQ
What is the maximum operating supply voltage for OPA832IDRG4?
The OPA832IDRG4 supports a maximum single-supply voltage of +11V and a maximum dual-supply voltage of ±5.5V, as specified in its Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. At +11V, quiescent current remains within 5.5mA, and small-signal bandwidth is maintained at ≥55MHz over temperature.
Does OPA832IDRG4 support true single-supply operation with input signals below ground?
Yes. The OPA832IDRG4 input stage allows input voltages as low as −0.5V on a +5V supply (and −0.2V at +3.3V), enabling direct interfacing with CCD sensors, piezoelectric transducers, and other bipolar-output sources without level-shifting circuitry - a key enabler for DC-coupled ultrasound and imaging designs.
What is the typical NTSC video performance of OPA832IDRG4 at 150Ω load?
At RL = 150Ω, the OPA832IDRG4 achieves 0.11% differential gain and 0.14° differential phase under +5V single-supply conditions - meeting EIA-770.1 broadcast video specifications. Performance degrades only marginally (to 0.12%/0.16°) at −40°C to +85°C, confirming robustness in consumer and industrial video systems.
Can OPA832IDRG4 drive four 150Ω video loads simultaneously?
Yes. The OPA832IDRG4 maintains 0.11% dG / 0.14° dP with one 150Ω load and degrades only to 0.20% dG / 0.25° dP with four parallel 150Ω loads - verified in TI's composite video dG/dP characterization. Output current capability (≥52mA sourcing/sinking at +5V) ensures stable drive without external buffers.
Is OPA832IDRG4 pin-compatible with other members of the OPA83x family?
No. The OPA832IDRG4 in SOT23-5 (DBV) has a unique 5-pin pinout (Output/−VS/Noninv/+VS/Inv). The SO-8 variant (OPA832ID) uses an 8-pin layout with NC pins and different terminal assignments. Neither variant shares pinout with OPA830 or OPA2832 - each requires dedicated PCB layout.
