Product details
Overview
THS4032CDGNRG4 from Texas Instruments is a dual-channel, ultra-low-noise (1.2nV/√Hz), high-speed voltage-feedback operational amplifier in an 8-pin HVSSOP package. It delivers 100MHz bandwidth at G = 2, 100V/μs slew rate, –90dBc THD at 1MHz (RL = 1kΩ), ±15V operation, and 200mA output drive - optimized for precision analog signal conditioning in data acquisition and imaging front-ends.
For engineers reviewing the THS4032CDGNRG4 datasheet, THS4032CDGNRG4 pinout, THS4032CDGNRG4 application, or THS4032CDGNRG4 equivalent, key selection criteria include input voltage noise density, channel-to-channel crosstalk (–61dBc), thermal performance (RθJA = 52.0°C/W in HVSSOP), unity-gain stability, and dual-channel layout efficiency in space-constrained PCBs.
Technical Context
The THS4032CDGNRG4 employs a complementary bipolar 30V process with GHz fT transistors, enabling voltage-feedback architecture with wide bandwidth, fast settling (70ns to 0.1%), and low distortion. Its internal compensation ensures unity-gain stability while maintaining 120MHz unity-gain bandwidth.
Designed for split-supply (±4.5V to ±16V) or single-supply (9V to 32V) operation, it features rail-to-rail input common-mode range (±14.3V at ±15V supply) and robust output drive into 150Ω or 1kΩ loads - critical for driving SAR ADCs and active filters without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (G = 2) | 100MHz (–3dB); enables full-spectrum fidelity for video, ultrasound, and DAQ signals up to 50MHz Nyquist |
| Slew Rate | 100V/μs; supports clean 20Vpp step response in ≤200ns without slewing distortion |
| Voltage Noise | 1.2nV/√Hz @ >10kHz; preserves SNR in low-level sensor and ADC driver stages |
| THD (1MHz, RL = 1kΩ) | –90dBc; ensures <0.001% harmonic contamination in precision measurement paths |
| Output Drive | 200mA (typical); directly drives 150Ω cables or ADC input networks without external buffers |
| Supply Range | ±4.5V to ±16V; compatible with industrial ±12V and test-equipment ±15V rails |
| Crosstalk (Ch-A to Ch-B) | –61dBc @ 1MHz; maintains channel isolation in dual-signal acquisition systems |
Pinout & Package
THS4032CDGNRG4 uses the DGN (8-pin HVSSOP) package: 3.0mm × 4.9mm body with exposed thermal pad. The thermal pad must be connected to a large copper plane for optimal RθJB = 24.5°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current output node; requires local 0.1μF bypass and series isolation resistor for >10pF capacitive loads |
| 1IN– | Channel 1 inverting input | Differential input node; matched impedance routing recommended to minimize imbalance-induced distortion |
| 1IN+ | Channel 1 noninverting input | High-impedance input; sensitive to PCB leakage and EMI - guard ring recommended |
| VCC– | Negative power supply | Return path for both channels; separate low-inductance ground plane connection required |
| 2IN+ | Channel 2 noninverting input | Independent input for second signal path; no shared offset nulling pins (unlike THS4031) |
| 2IN– | Channel 2 inverting input | Matched to 1IN– for consistent gain-setting network design across both channels |
| 2OUT | Channel 2 output | Electrically isolated from 1OUT; crosstalk specification validates independent small-signal integrity |
| VCC+ | Positive power supply | Primary supply rail; decoupling with 0.1μF ceramic + 4.7μF tantalum per channel recommended |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 1.2nV/√Hz enables sub-16-bit ENOB preservation when driving high-resolution SAR ADCs |
| Unity-gain stable | 120MHz unity-gain bandwidth allows use in gain-of-1 buffer, integrator, and filter configurations without external compensation |
| High output current | 200mA drive capability eliminates need for external current boosters in cable-driving applications |
| Low THD at high frequency | –90dBc @ 1MHz (RL = 1kΩ) meets spectral purity requirements for vector signal transceivers and DAQ systems |
| HVSSOP thermal performance | RθJA = 52.0°C/W (vs. 120.6°C/W for SOIC) enables higher sustained output power in compact layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032D | Same die in 8-pin SOIC package; RθJA = 120.6°C/W vs. 52.0°C/W for DGN | Larger footprint; lower thermal efficiency limits sustained output current in dense layouts | Select THS4032D only if SOIC compatibility or legacy board reuse is required |
| OPA2691IDGKT | Higher 320MHz GBW but 2.1nV/√Hz noise; 110V/μs slew; not unity-gain stable | Requires external compensation; unsuitable for G = 1 buffers or active filters without redesign | Choose OPA2691IDGKT only for >200MHz closed-loop bandwidth needs where noise is secondary |
Compared with THS4032D and OPA2691IDGKT, THS4032CDGNRG4 uniquely balances ultra-low noise, unity-gain stability, and superior thermal performance in a space-efficient HVSSOP - making it optimal for thermally constrained, multi-channel precision analog systems.

FAQ
What is the maximum operating supply voltage for THS4032CDGNRG4?
The THS4032CDGNRG4 supports dual-supply operation from ±4.5V to ±16V (32V total), with absolute maximum ratings specifying VCC– to VCC+ ≤ 33V. Operation beyond ±16V risks exceeding junction temperature limits and voiding reliability guarantees. Always verify thermal dissipation using RθJA = 52.0°C/W for the HVSSOP package when operating near max supply.
Does THS4032CDGNRG4 have offset nulling pins like THS4031?
No, THS4032CDGNRG4 does not include offset nulling pins. Unlike the single-channel THS4031 (which provides NULL pins 1 and 8), the dual-channel THS4032 has no dedicated offset adjustment terminals. Its typical input offset voltage is 0.3mV (25°C), with full-range drift of 2μV/°C - sufficient for most high-speed applications without trimming.
Can THS4032CDGNRG4 drive a 75Ω video load directly?
Yes, THS4032CDGNRG4 can directly drive a 75Ω load with full swing: at ±15V supply, it delivers ±12.9V into 250Ω and ±13.6V into 1kΩ; extrapolation and typical 200mA output current confirm capability for 75Ω with appropriate series isolation (e.g., 75Ω resistor) to maintain stability. Measured differential gain/phase errors (0.015%/0.025°) validate broadcast video compliance.
What is the channel-to-channel crosstalk specification for THS4032CDGNRG4?
The THS4032CDGNRG4 specifies –61dBc channel-to-channel crosstalk at 1MHz under standard conditions (VCC = ±5V or ±15V). This value is measured between Channel A and Channel B outputs and confirms effective isolation for dual-signal acquisition, I/Q processing, or independent filter paths without measurable intermodulation.
Is THS4032CDGNRG4 unity-gain stable, and what is its unity-gain bandwidth?
Yes, THS4032CDGNRG4 is unity-gain stable with a minimum unity-gain bandwidth of 100MHz and typical value of 120MHz (closed-loop, VCC = ±15V). This allows safe use in G = 1 buffer, integrator, or active filter configurations without external compensation components - a key differentiator from decompensated high-speed op-amps.
