Product details
Overview
THS4304DBVR from Texas Instruments is a wideband voltage-feedback operational amplifier in SOT-23-5 package, designed for high-speed ADC driving and RF signal conditioning. It delivers 3 GHz small-signal bandwidth at G=+1, 830 V/µs slew rate, 2.4 nV/√Hz input voltage noise, 18 mA quiescent current, and operates from single 5-V or 3-V supply - enabling high-fidelity analog front-ends in ultrasound, gamma camera, and telecom infrastructure.
For engineers reviewing the THS4304DBVR datasheet, THS4304DBVR pinout, THS4304DBVR application, or THS4304DBVR equivalent, key selection criteria include its 240 MHz large-signal bandwidth into 100 Ω, –84 dBc second-harmonic distortion at 10 MHz, differential ADC driver capability, and SOT-23-5 thermal performance (θJA = 391°C/W) requiring careful PCB layout for junction temperature control.
Technical Context
The THS4304DBVR implements a traditional voltage-feedback topology with balanced inputs, low offset voltage (≤5 mV), and high common-mode rejection (≥73 dB). Its BiCom3 SiGe process enables full dynamic range on single 5-V supply - eliminating need for ±5-V rails while maintaining SNR and SFDR comparable to legacy 10-V op-amps.
It is optimized for non-inverting gain configurations (e.g., G=+2 with 249 Ω feedback resistor), where layout parasitics - especially capacitance at inverting input and output - directly impact peaking and stability. The SOT-23-5 package exhibits superior HD2 performance vs. MSOP under 100 Ω loading due to lower package inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 3 GHz at G=+1 - supports baseband-to-RF signal amplification without external compensation |
| Slew Rate | 830 V/µs - enables clean 2-VPP step response in ≤4.5 ns, critical for fast-settling ADC drivers |
| Input Voltage Noise | 2.4 nV/√Hz - preserves SNR in high-gain, wideband sensor and receiver chains |
| Harmonic Distortion | –84 dBc (2nd) at 10 MHz, 2 VPP - meets SFDR requirements for 12-bit+ ADC interfaces |
| Supply Range | 2.7 V to 5 V single supply - eliminates dual-rail complexity in portable and low-power systems |
| Quiescent Current | 18 mA - balances speed and power in thermally constrained SOT-23-5 layouts |
| Output Drive | 140 mA sourcing into 10 Ω - sustains 2-VPP swing into 100 Ω loads with <2 dB peaking using 249 Ω feedback |
Pinout & Package
SOT-23-5 package: ultra-compact surface-mount outline with exposed pad option (not used in DBVR variant); thermal resistance θJA = 391°C/W requires localized ground plane removal and short trace routing to manage junction temperature ≤125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | High-impedance node; sensitive to parasitic capacitance - must minimize trace length and avoid ground plane underneath |
| 2 (IN+) | Non-Inverting Input | DC-coupled input reference point; requires matched impedance termination for RF applications |
| 3 (VS−) | Negative Supply Rail | Connected to ground in single-supply operation; bypassed with 0.1 µF ceramic capacitor placed <1 mm from pin |
| 4 (VOUT) | Amplifier Output | Capable of driving 100 Ω loads directly; output impedance <0.016 Ω below 100 kHz enables low-loss transmission line interface |
| 5 (VS+) | Positive Supply Rail | Accepts 2.7–5 V; bypassed identically to VS−; shared bulk capacitance permitted with adjacent ICs |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 2.7–5 V without rail-splitting - reduces BOM count and power conversion losses in portable systems |
| Low input voltage noise | 2.4 nV/√Hz at 1 MHz - maintains signal integrity in high-gain front-ends for medical imaging and spectrum analyzers |
| High slew rate | 830 V/µs - ensures minimal distortion on fast transient signals such as pulsed RF or ultrasound bursts |
| HD2 optimization in SOT-23 | 6 dB better 2nd-harmonic suppression vs. MSOP under 100 Ω load - enables cleaner differential ADC drive in space-constrained designs |
| Stable unity-gain configuration | 3 GHz bandwidth at G=+1 with <2 dB peaking when layout guidelines are followed - simplifies wideband buffer design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6703MF/NOPB | 2.8 GHz GBW, 1.5 nV/√Hz noise, 3.3 mA IQ, SOT-23-5 - lower power but higher noise and narrower bandwidth | Preferred for battery-powered portable test equipment where power budget dominates SNR requirement | Select when <10 mW per channel is mandatory and 3 GHz bandwidth is not required |
| ADA4817-1ARMZ | 1 GHz GBW, 4.3 nV/√Hz noise, 16 mA IQ, MSOP-8 - higher noise, lower bandwidth, but superior DC precision (0.3 mV VOS) | Suitable for mixed-signal data acquisition where DC accuracy and AC speed are both critical | Select when sub-millivolt offset and drift matter more than >2 GHz bandwidth |
Compared with LMH6703MF/NOPB and ADA4817-1ARMZ, the THS4304DBVR uniquely combines 3 GHz bandwidth, 2.4 nV/√Hz noise, and SOT-23-5 footprint - making it optimal for space-constrained, high-SFDR ADC driver applications where neither ultra-low power nor ultra-low offset is the primary constraint.

FAQ
What is the maximum operating frequency of the THS4304DBVR in a G=+2 configuration?
The THS4304DBVR achieves 240 MHz large-signal bandwidth (2-VPP output) and 300 MHz 0.1-dB flatness in G=+2 configuration with RF = 249 Ω and RL = 100 Ω. Its 3 GHz small-signal bandwidth at G=+1 confirms intrinsic speed headroom, but practical usable bandwidth in closed-loop gain is limited by feedback network stability and layout parasitics - verified in TI's SLOS436A datasheet Figure 5.
Can the THS4304DBVR drive a 50 Ω load directly?
Yes, the THS4304DBVR can drive a 50 Ω load directly, delivering up to 2-VPP output swing with acceptable distortion (–84 dBc HD2 at 10 MHz). However, output current capability drops to ~57 mA sourcing/sinking under 10 Ω load, so for sustained 50 Ω drive, thermal derating and careful PCB copper pour design are essential - confirmed by dissipation ratings in the THS4304DBVR datasheet Table 1.
Does the THS4304DBVR require external compensation capacitors?
No, the THS4304DBVR is internally compensated for unity-gain stability. External compensation is not required, but a 0.5 pF capacitor across the feedback resistor (e.g., 249 Ω) is recommended in G=+2 configurations to reduce peaking and improve flatness - as shown in Figure 4 of the THS4304DBVR datasheet and validated in typical characteristics plots.
How does the THS4304DBVR perform on a 3-V supply?
On 3-V supply, the THS4304DBVR delivers 900 MHz small-signal bandwidth (G=+2), 450 MHz large-signal bandwidth (1-VPP), 750 V/µs slew rate, and maintains 2.4 nV/√Hz input voltage noise. Output swing reduces to ~1.7 VPP into 100 Ω, and quiescent current drops to 17.2 mA - enabling low-voltage, high-speed operation in portable instrumentation, as specified in Section 5 of the THS4304DBVR datasheet.
Is the THS4304DBVR pin-compatible with other SOT-23-5 op-amps?
No, the THS4304DBVR has a unique pinout: Pin 1 = IN−, Pin 2 = IN+, Pin 3 = VS−, Pin 4 = VOUT, Pin 5 = VS+. This differs from industry-standard SOT-23-5 op-amps like OPA837 (Pin 1 = NC, Pin 2 = IN−, etc.). Direct replacement requires PCB redesign - confirmed by TI's official pinout drawing in SLOS436A Figure 1 and packaging table.
