Product details
Overview
OPA3832IDR from Texas Instruments is a triple, low-power, high-speed, fixed-gain operational amplifier optimized for single-supply video line driving and CCD imaging channel buffering. It delivers 80MHz bandwidth (G = +2), 350V/µs slew rate, 4.9VPP output swing on +5V supply, rail-to-rail output swing to within 30mV of ground and 60mV of VS, and 9.3nV/√Hz input voltage noise - enabling high-fidelity analog signal conditioning in portable consumer electronics and ultrasound front-ends.
For engineers reviewing the OPA3832IDR datasheet, OPA3832IDR pinout, OPA3832IDR application, or OPA3832IDR equivalent, this page provides verified circuit role, validated SO-14 package mapping, confirmed disable-control timing (20ns enable / 40µs disable), NTSC-compliant differential gain (0.11%) and phase (0.14°), and real-world thermal resistance (85°C/W) - all extracted from TI SBOS370A revision August 2008.
Technical Context
The OPA3832IDR integrates three identical fixed-gain amplifier channels with complementary common-emitter outputs, supporting both inverting (G = –1) and noninverting (G = +2) configurations via internal 400Ω feedback and gain-setting resistors. Its input range extends below ground and to within 1.7V of the positive supply, enabling true single-supply operation from +3V to +11V or dual supplies from ±1.5V to ±5.5V.
Each channel features independent digital disable control (active-low DIS pins), delivering 0.7mA quiescent current per channel in shutdown mode at +5V, 20ns fast enable time, and –75dB off-isolation at 5MHz - critical for power-aware multiplexed converter driver systems like those using ADS826.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain, triple-opamp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3832IPWR | TSSOP-14 package (100°C/W θJA), same electrical specs, 2000-piece tape-and-reel | Higher thermal resistance requires derating above 65°C ambient; smaller footprint suits space-constrained layouts | Select for compact PCBs where thermal margin permits; verify board-level heat dissipation |
| OPA2832IDR | Dual-channel version (SO-8), identical per-channel specs but no third amplifier or DIS C pin | Not suitable for triple-signal-path systems; eliminates one channel's disable control and output capability | Choose only when exactly two matched channels are required - avoids over-spec'ing channel count |
Compared with OPA3832IPWR, the OPA3832IDR offers lower thermal resistance (85°C/W vs 100°C/W) for higher sustained output current in industrial environments; compared with OPA2832IDR, it provides full triple-channel functionality essential for RGB video or 3-tap CCD architectures - neither is pin-compatible nor drop-in.

FAQ
What supply voltage ranges does the OPA3832IDR support?
The OPA3832IDR operates from +3V to +11V single supply or ±1.5V to ±5.5V dual supply. Minimum operating voltage is +2.8V (typ) or ±1.4V (min), and maximum is +11V or ±5.5V. At +3.3V, it maintains 90MHz small-signal bandwidth and 150V/µs slew rate - making it viable for modern low-voltage portable designs. The OPA3832IDR's input common-mode range extends below ground, simplifying level-shifting in mixed-supply systems.
Does the OPA3832IDR require external gain-setting resistors?
No, the OPA3832IDR integrates precision 400Ω internal feedback and gain-setting resistors for both G = +2 (noninverting) and G = –1 (inverting) configurations. This eliminates external components, reduces board area, and ensures ±0.3% gain error at +25°C - far tighter than typical discrete resistor matching. The OPA3832IDR's internal network is factory-trimmed and thermally tracked, maintaining stability across –40°C to +85°C without recalibration.
How does the disable function work on the OPA3832IDR?
The OPA3832IDR features three independent active-low disable pins (DIS A, DIS B, DIS C), one per channel. When pulled low, each channel enters high-impedance output state with <0.7mA supply current per disabled channel at +5V. Enable time is 20ns (typ), disable time is 40µs (typ), and off-isolation exceeds –75dB at 5MHz. The OPA3832IDR's per-channel control enables dynamic power management in multiplexed systems - for example, disabling two CCD taps while reading the third.
What is the output drive capability of the OPA3832IDR?
The OPA3832IDR delivers ±75mA sourcing/sinking current into 1kΩ and ±4.6V swing into 150Ω on +5V supply. Short-circuit output current is 100mA (typ), and closed-loop output impedance is 0.2Ω below 100kHz. This drive strength supports direct connection to 75Ω/150Ω video lines and multiple parallel ADC inputs without external buffers. The OPA3832IDR maintains low distortion (–54dBc 2nd-harmonic) even under heavy load, ensuring signal fidelity in demanding applications.
Is the OPA3832IDR suitable for NTSC video applications?
Yes, the OPA3832IDR is explicitly characterized for NTSC video: differential gain is 0.11% (typ) and differential phase is 0.14° (typ) into 150Ω, meeting broadcast-grade requirements without external compensation. Its 80MHz bandwidth, low 9.3nV/√Hz noise, and rail-to-rail output swing to within 30mV of ground ensure accurate luminance/chrominance separation and minimal color artifacts. The OPA3832IDR's performance is validated across temperature and supply variations - confirming robustness in consumer video products.
