Product details
Overview
OPA3832IPWR 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 V+, and 9.3nV/√Hz input voltage noise. It operates from +3V to +11V single supply or ±1.5V to ±5.5V dual supply.
For engineers reviewing the OPA3832IPWR datasheet, OPA3832IPWR pinout, OPA3832IPWR application, or OPA3832IPWR equivalent, this page provides verified electrical specifications, TSSOP-14 package details, disable-control timing, NTSC-compliant video performance, and validated alternatives for portable consumer electronics, ultrasound front-ends, and multiplexed ADC driver designs.
Technical Context
The OPA3832IPWR integrates three identical fixed-gain op-amps with complementary common-emitter outputs enabling rail-to-rail output swing and high current drive (±75mA sourcing/sinking at +5V). Its internal 400Ω feedback network sets fixed gain of +2 or –1, eliminating external resistors and minimizing layout sensitivity.
Each channel features independent digital disable control (active-low DIS pins), enabling dynamic power management with 20ns enable time and 40µs disable time. The device maintains low harmonic distortion (–54dBc 2nd-harmonic at 5MHz, RL = 150Ω) and tight NTSC video specs (0.11% differential gain, 0.14° differential phase) across temperature and supply variations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple fixed-gain operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3832IDR | Same die, SO-14 package (D suffix); 85°C/W thermal resistance vs 100°C/W for TSSOP-14 | Better thermal performance in high-power-density layouts; larger footprint (8.65mm × 3.9mm) | Select OPA3832IDR for higher ambient temperature operation (>70°C) or where reflow compatibility with legacy SOIC footprints is required. |
| THS3203DR | Dual-channel (not triple), 220MHz bandwidth, higher supply current (6.5mA/ch), no integrated disable function | Lacks third channel and independent disable control; requires external gain resistors | Choose THS3203DR only when higher bandwidth is mandatory and channel count can be reduced via system-level multiplexing. |
Compared with OPA3832IDR, the OPA3832IPWR offers smaller board area and finer pitch for space-constrained portable designs, while THS3203DR trades channel count and integration for raw speed - making OPA3832IPWR optimal for compact, power-aware triple-channel video and imaging systems.

FAQ
What supply voltage ranges does the OPA3832IPWR support?
The OPA3832IPWR operates from +3V to +11V on single supply or ±1.5V to ±5.5V on dual supply. Minimum functional voltage is +2.8V (typ), verified across temperature. At +3.3V, it delivers 90MHz bandwidth (G = +2) and –60dBc 2nd-harmonic distortion at 5MHz - making OPA3832IPWR suitable for modern low-voltage portable systems without sacrificing speed or linearity.
Does the OPA3832IPWR require external gain-setting resistors?
No. The OPA3832IPWR integrates internal 400Ω feedback and gain-setting resistors, providing fixed gains of +2 (non-inverting) or –1 (inverting) without external components. This eliminates resistor matching errors, saves PCB area, and ensures consistent channel-to-channel gain accuracy (±0.3% typical at +25°C), which is critical in multi-channel video and imaging applications where OPA3832IPWR is deployed.
How does the disable function work on the OPA3832IPWR?
Each channel (A/B/C) has a dedicated active-low disable pin (DIS A/B/C). Pulling a DIS pin low places that channel's output in high-impedance state with <2mV turn-off glitch and 40µs disable time. Supply current drops to 0.7mA total (all channels disabled) at +5V. This per-channel control enables dynamic power management in battery-powered ultrasound and portable video systems using OPA3832IPWR.
What is the output drive capability of the OPA3832IPWR?
The OPA3832IPWR delivers ±75mA sourcing/sinking current into 150Ω loads at +5V supply, with rail-to-rail swing to within 0.18V of ground and 0.4V of V+. It maintains 4.9VPP output into 1kΩ and exhibits low closed-loop output impedance (0.2Ω up to 100kHz). This drive strength allows direct interfacing with 75Ω video lines and SAR ADC inputs without external buffers - a key design advantage of the OPA3832IPWR.
Is the OPA3832IPWR suitable for NTSC video applications?
Yes. The OPA3832IPWR is characterized for NTSC video performance: 0.11% differential gain and 0.14° differential phase (RL = 150Ω), meeting SMPTE RP 168 standards. Its low 9.3nV/√Hz input voltage noise, 80MHz bandwidth, and fast 46ns settling time ensure accurate composite video signal amplification - confirming OPA3832IPWR as a qualified solution for broadcast-grade and portable video line drivers.
