Product details
Overview
OPA832IDBVR from Texas Instruments is a low-power, single-supply, fixed-gain +2 voltage-feedback operational amplifier optimized for video line driving and high-fidelity analog signal conditioning. It delivers 80MHz small-signal bandwidth (G = +2), 350V/µs slew rate, 4.9VPP output swing on +5V supply, 9.3nV/√Hz input voltage noise, and operates from +2.8V to +11V single supply. It serves as a precision buffer in portable video interfaces and CCD imaging channels.
For engineers reviewing the OPA832IDBVR datasheet, OPA832IDBVR pinout, OPA832IDBVR application, or OPA832IDBVR equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional trade-offs for single-supply high-speed amplification.
Technical Context
The OPA832IDBVR uses a voltage-feedback architecture with internal 400Ω RF/RG resistors, enabling stable +2 gain without external components. Its complementary common-emitter output stage supports rail-to-rail output swing - within 30mV of ground and 130mV of VS - while maintaining low differential gain/phase error (0.11% / 0.14° NTSC) at 150Ω load.
Input range extends below ground and to within 1.7V of VS, supporting true single-supply operation down to +2.8V. The device achieves 200MHz gain-bandwidth product and low distortion (−64dBc 2nd-harmonic @ 5MHz, 2VPP, 150Ω), making it suitable as an input buffer for 3V/5V CMOS ADCs and consumer video DAC interfaces.
Key Specifications

| Slew Rate | 350V/µs - supports clean 2VPP transient response with ≤4.6ns rise time, critical for composite video pulse integrity. |
| Output Voltage Swing | ±4.6V on +5V supply into 150Ω - delivers 4.9VPP differential swing, matching standard 75Ω video line requirements. |
| Input Voltage Noise | 9.3nV/√Hz - preserves wide dynamic range in low-level CCD imaging and ultrasound front-end stages. |
| Supply Range | +2.8V to +11V single supply - allows direct integration with 3.3V and 5V systems without level-shifting circuitry. |
| Quiescent Current | 3.9mA at +5V - enables battery-powered portable electronics with thermal headroom in SOT23-5 package. |
| NTSC Differential Gain/Phase | 0.11% / 0.14° - meets broadcast-grade video line driver specifications for consumer and medical imaging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain, single-supply video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA830IDBVR | Higher bandwidth (100MHz), higher quiescent current (5.5mA), no internal feedback resistors - requires external RF/RG for gain setting. | Used where adjustable gain (e.g., +1/+2/−1) or wider bandwidth is needed; less suitable for cost-sensitive fixed-gain designs. | Select OPA830IDBVR only if programmable gain or >80MHz bandwidth is required; OPA832IDBVR offers lower power and simpler layout. |
| LMH6629MF/NOPB | Higher slew rate (1000V/µs), higher noise (12.5nV/√Hz), SO-8 only, no internal resistors, higher supply current (12.5mA). | Targeted at high-fidelity test equipment and radar receivers where speed dominates power/noise trade-offs. | Choose LMH6629MF/NOPB only for >500MHz small-signal bandwidth needs; OPA832IDBVR provides better noise/power balance for portable video. |
Compared with OPA830IDBVR and LMH6629MF/NOPB, the OPA832IDBVR uniquely combines internal +2 gain, 3.9mA quiescent current, and 0.11% NTSC differential gain - making it the most integrated, lowest-power solution for production video line drivers in SOT23-5 form factor.

FAQ
What is the maximum supply voltage for OPA832IDBVR?
The absolute maximum supply voltage for OPA832IDBVR is +12VDC for single-supply operation, but its specified operating range is +2.8V to +11V. Operation above +11V risks permanent damage and violates the Absolute Maximum Ratings table in the SBOS266E datasheet. For reliable long-term use, stay within the +2.8V to +11V range, with recommended nominal supplies at +3.3V or +5V.
Does OPA832IDBVR require external gain-setting resistors?
No, OPA832IDBVR does not require external gain-setting resistors because it integrates internal 400Ω RF and RG resistors configured for fixed +2 gain. This eliminates resistor matching errors and layout sensitivity. External resistors are unnecessary unless modifying gain via alternate configurations - which voids guaranteed performance specs and is not supported by TI's characterization.
What is the output swing capability of OPA832IDBVR on a +5V supply?
On a +5V single supply with RL = 150Ω to VCM = 2V, OPA832IDBVR delivers a minimum output swing of 4.4VPP (from 0.20V to 4.60V), per Electrical Characteristics Table on page 4 of SBOS266E. At room temperature and light load (1kΩ), it achieves up to 4.9VPP - sufficient to drive standard 75Ω video lines with headroom for sync pulses.
Can OPA832IDBVR be used in dual-supply configurations?
Yes, OPA832IDBVR supports dual-supply operation from ±1.4V to ±5.5V. Its input common-mode range extends to within 1.7V of either rail, and output swings to within 30mV of each supply. The device is fully characterized at ±5V in the datasheet, with 99MHz small-signal bandwidth (G = −1) and −64dBc harmonic distortion at 5MHz - confirming robust bipolar operation.
What is the thermal resistance (θJA) of the OPA832IDBVR SOT23-5 package?
The junction-to-ambient thermal resistance (θJA) for OPA832IDBVR in the SOT23-5 (DBV) package is 150°C/W, as specified in the Thermal Characteristics table on pages 3–5 of SBOS266E. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with PCB copper area and thermal vias. At 3.9mA quiescent current and +5V supply, power dissipation is ~19.5mW, resulting in <3°C junction rise under typical conditions.
