Product details
Overview
OPA2832IDR from Texas Instruments is a dual, low-power, high-speed, fixed-gain operational amplifier optimized for single-supply video line driving and CCD imaging channels. It delivers 75MHz small-signal bandwidth (G = +2), 350V/µs slew rate, and 4.9VPP output swing on +5V supply, with rail-to-rail output swing to within 30mV of ground and 60mV of VS.
For engineers reviewing the OPA2832IDR datasheet, OPA2832IDR pinout, OPA2832IDR application, or OPA2832IDR equivalent, this page provides verified specifications, SO-8 package details, differential gain/phase performance for NTSC, low-noise operation (9.3nV/√Hz), and validated alternatives for portable consumer electronics and ultrasound front-ends.
Technical Context
The OPA2832IDR integrates two identical fixed-gain op-amps with internal 400Ω feedback and gain-setting resistors, supporting only G = +1, +2, and –1 configurations. Its complementary common-emitter output stage enables true rail-to-rail output swing while maintaining low distortion across wide signal swings.
Designed for single-supply operation from +3V to +11V (or ±1.5V to ±5.5V), it features input voltage range extending below ground and up to 1.7V below VS, enabling direct interfacing with CMOS ADCs and video DACs without level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain, high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2830IDR | Adjustable gain (external RF/RG); higher 100MHz bandwidth at G = +2; 8.5mA IQ | Requires external resistors; better for programmable gain stages or wider bandwidth needs | Select OPA2830IDR when gain flexibility or >75MHz BW is required; not pin-compatible |
| THS3202D | Higher 1.8GHz GBW; 3000V/µs slew rate; 12mA IQ; no internal gain resistors | Targeted at RF/IF signal chains, not video-optimized; lacks NTSC dG/dP characterization | Choose THS3202D for ultra-high-speed non-video applications; requires full external feedback network |
Compared with OPA2832IDR, OPA2830IDR offers gain configurability at the cost of added external components and slightly higher power, while THS3202D delivers extreme speed but sacrifices video-specific linearity and integrated simplicity.

FAQ
What is the maximum operating supply voltage for the OPA2832IDR?
The OPA2832IDR supports a maximum single-supply voltage of +11V and a maximum dual-supply voltage of ±5.5V. Absolute maximum ratings specify +12.5V on +VS and –6.5V on –VS, but functional operation is guaranteed only within the specified ranges. Exceeding +11V or –5.5V may cause permanent damage or parametric shift.
Does the OPA2832IDR require external gain-setting resistors?
No, the OPA2832IDR integrates internal 400Ω feedback and gain-setting resistors, supporting fixed gains of +1, +2, and –1 without external components. This eliminates resistor matching errors and PCB area, making it ideal for space-constrained video and imaging designs where gain stability is essential.
Can the OPA2832IDR drive a 75Ω video load directly?
Yes, the OPA2832IDR is characterized to drive 150Ω loads with ±4.6V swing on +5V supply, and its ±75mA output current capability allows direct driving of standard 75Ω video lines with proper termination. For optimal NTSC performance, use the recommended 150Ω load per TI SBOS327C Figure 61.
What is the input voltage range of the OPA2832IDR when powered from +5V?
With +5V single supply, the OPA2832IDR input common-mode range extends from –0.5V to +3.0V. The least positive input voltage is –0.5V (allowing inputs below ground), and the most positive input voltage is +3.0V at +25°C - sufficient to interface with 0–2V video DAC outputs and CCD bias references.
Is the OPA2832IDR suitable for driving ADC inputs in portable systems?
Yes, the OPA2832IDR is well-suited for driving SAR and sigma-delta ADC inputs in portable systems. Its 75MHz bandwidth, 350V/µs slew rate, and rail-to-rail output ensure accurate settling of fast step inputs, while its 7.8mA quiescent current per channel supports battery-operated designs without compromising acquisition fidelity.
