Product details
Overview
OPA2832IDGKRG4 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, 4.9VPP output swing on +5V supply, rail-to-rail output, and input range extending to ground - enabling direct interfacing with 3V/5V CMOS ADCs in portable consumer electronics.
For engineers reviewing the OPA2832IDGKRG4 datasheet, OPA2832IDGKRG4 pinout, OPA2832IDGKRG4 application, or OPA2832IDGKRG4 equivalent, key selection criteria include its fixed +2 gain architecture, ±4.6V output swing into 150Ω, 9.3nV/√Hz input voltage noise, and MSOP-8 package compatibility with space-constrained video signal chains.
Technical Context
The OPA2832IDGKRG4 integrates two identical, internally compensated amplifiers with fixed +2V/V noninverting gain and complementary common-emitter outputs. Its input stage operates down to ground on single supplies and supports input voltages up to 3.3V with +5V supply, while the output swings within 30mV of ground and 60mV of VS.
It features internal 400Ω feedback and gain-setting resistors (RF/RG), eliminating external components for G = +2 operation. The device maintains low harmonic distortion (–64dBc 2nd-harmonic, RL = 150Ω, 5MHz) and tight DC performance (±0.3% gain error, ±1.5mV input offset) across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 75MHz at G = +2, VO ≤ 0.5VPP - enables high-fidelity NTSC/PAL video signal amplification without phase loss. |

| Output Swing | ±4.6V into 150Ω on +5V supply - delivers full 4.9VPP differential swing for 150Ω video loads. |
| Input Voltage Noise | 9.3nV/√Hz above 1MHz - preserves SNR in wide-dynamic-range CCD imaging front-ends. |
| Quiescent Current | 7.8mA total (VS = +5V) - balances speed and power for battery-powered portable electronics. |
| Gain Error | ±0.3% at +25°C - ensures accurate signal scaling without calibration in fixed-gain video buffers. |
| NTSC Differential Gain | 0.11% - meets broadcast video fidelity requirements for consumer-grade line drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2830IDGKR | Adjustable gain (external RF/RG); higher 100MHz bandwidth at G = +2 but 10.5mA supply current. | Used where programmable gain or wider bandwidth is required; not pin-compatible due to different internal resistor topology. | Select OPA2830IDGKR only when gain flexibility outweighs BOM simplification and power savings of OPA2832IDGKRG4. |
| LMH6629MA/NOPB | Single-channel, 1.5GHz GBW, 3.5mA/channel, but no internal gain-setting resistors and limited rail-to-rail output swing. | Targeted at ultra-high-frequency test equipment; lacks integrated video-specific specs (dG/dP) and fixed-gain convenience. | Choose LMH6629MA/NOPB for >200MHz small-signal applications where OPA2832IDGKRG4's 75MHz limit is insufficient. |
Compared with OPA2832IDGKRG4, the OPA2830IDGKR trades fixed-gain simplicity for design flexibility and bandwidth, while the LMH6629MA/NOPB offers extreme speed at the cost of video fidelity specs, power efficiency, and dual-channel integration - making OPA2832IDGKRG4 optimal for cost-sensitive, space-constrained, broadcast-compliant video and imaging systems.

FAQ
What is the operating supply voltage range for the OPA2832IDGKRG4?
The OPA2832IDGKRG4 supports a flexible supply range: +3V to +11V for single-supply operation and ±1.5V to ±5.5V for dual-supply use. At +5V, it draws 7.8mA quiescent current and delivers full 4.9VPP output swing - making it ideal for standard 5V systems without level-shifting overhead. Minimum operating voltage is +2.8V, enabling compatibility with 3.3V logic domains.
Does the OPA2832IDGKRG4 require external gain-setting resistors?
No. The OPA2832IDGKRG4 integrates precise 400Ω internal feedback and gain-setting resistors, enabling fixed +2V/V noninverting and −1V/V inverting configurations without external components. This eliminates resistor matching errors, reduces PCB area, and improves temperature stability of gain accuracy (±0.3% at +25°C).
What is the output voltage swing capability of the OPA2832IDGKRG4 on a +5V supply?
On a +5V supply, the OPA2832IDGKRG4 delivers ±4.6V output swing into a 150Ω load (4.9VPP), and ±4.75V into 1kΩ. Its rail-to-rail output stage swings to within 30mV of ground and 60mV of VS, maximizing dynamic range for ADC interfacing and video signal transmission without clipping.
Is the OPA2832IDGKRG4 suitable for NTSC/PAL video applications?
Yes. The OPA2832IDGKRG4 is explicitly characterized for video: 0.11% NTSC differential gain and 0.14° differential phase meet broadcast video fidelity standards. Its 75MHz bandwidth, low distortion (–64dBc 2nd-harmonic), and 150Ω drive capability make it a validated solution for CVBS, Y/C, and S-video line drivers in consumer and industrial video equipment.
What package type does the OPA2832IDGKRG4 use, and is thermal performance specified?
The OPA2832IDGKRG4 uses the MSOP-8 (DGK) package - a 3mm × 3mm, 0.65mm pitch surface-mount outline with exposed thermal pad. Its thermal resistance is 150°C/W (junction-to-ambient), and it is rated for operation from –40°C to +85°C. The exposed pad must be soldered to PCB copper for optimal thermal dissipation in high-output-current applications.
