Product details
Overview
THS4304DRG4 from Texas Instruments is a wideband voltage-feedback operational amplifier designed for high-speed analog signal chains operating on a single 5-V supply. It delivers 3-GHz small-signal bandwidth (G = +1), 830 V/µs slew rate, 2.4 nV/√Hz input voltage noise, and –84 dBc second-harmonic distortion at 10 MHz - enabling precision ADC driving in RF/telecom and ultrasound systems.
For engineers reviewing the THS4304DRG4 datasheet, THS4304DRG4 pinout, THS4304DRG4 application, or THS4304DRG4 equivalent, key selection criteria include single-supply operation down to 2.7 V, differential ADC driver capability with <4.5 ns settling to 1%, package-dependent harmonic performance (SOIC vs. MSOP/SOT-23), and BiCom3 process–enabled dynamic range preservation at low supply voltages.
Technical Context
The THS4304DRG4 implements a traditional voltage-feedback topology with balanced inputs, low offset voltage (≤5 mV), and high common-mode rejection (≥73 dB). Its BiCom3 silicon germanium process enables full performance on 5-V single supply - eliminating need for ±5-V rails while maintaining SNR and SFDR comparable to legacy 10-V op-amps.
It supports non-inverting and inverting configurations with gain-setting resistors (e.g., 249 Ω for G = +2); layout-critical parasitic management is required - including ground plane removal under the device and short, direct feedback traces - to preserve phase margin and avoid peaking above 300 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 3 GHz at G = +1 - enables baseband-to-RF signal conditioning without external gain stages |
| Slew Rate | 830 V/µs - supports fast transient fidelity for 2-VPP step signals in ADC front-ends |
| Input Voltage Noise | 2.4 nV/√Hz at 1 MHz - preserves SNR in low-amplitude, high-bandwidth sensor interfaces |
| Harmonic Distortion | –84 dBc (2nd) at 10 MHz, RL = 100 Ω - meets SFDR requirements for 12–14-bit ADC drivers |
| Supply Voltage Range | 2.7 V to 5 V - allows interoperability with 3.3-V and 5-V digital domains without level-shifting |
| Quiescent Current | 18 mA - balances power efficiency with RF-grade linearity in portable instrumentation |
| Output Voltage Swing | 3.7 VPP into 100 Ω at 5 V supply - delivers full-scale drive for 1-VPP ADC inputs with headroom |
Pinout & Package
THS4304DRG4 is packaged in an 8-pin SOIC (D package), with exposed pad not electrically connected. Thermal resistance θJA = 97.5°C/W enables stable operation up to 85°C ambient when properly mounted on standard FR-4 PCBs with 2-oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | Differential node for feedback network connection; sensitive to parasitic capacitance - requires short trace routing |
| 2 (IN+) | Non-Inverting Input | High-impedance input node; referenced to common-mode voltage (typically 2.5 V for 5-V supply) |
| 3 (VS−) | Negative Supply Rail | Ground reference for single-supply operation; must be decoupled with 0.1 µF ceramic capacitor |
| 4 (VOUT) | Amplifier Output | Capable of sourcing/sinking ≥100 mA into 10 Ω; drives 100 Ω loads directly with <2 dB peaking at G = +2 |
| 5 (NC) | No Internal Connection | Unused pin - must remain unconnected per TI design guidance to avoid parasitic coupling |
| 6 (NC) | No Internal Connection | Unused pin - no internal silicon connection; floating or grounded per layout best practice |
| 7 (VS+) | Positive Supply Rail | 5-V rail input; requires local 0.1 µF bypass capacitor placed ≤2 mm from pin |
| 8 (NC) | No Internal Connection | Unused pin - left unconnected; not tied to substrate or thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| Single 5-V supply operation | Eliminates dual-rail power design complexity while delivering 3-GHz bandwidth and 2-VPP output swing |
| BiCom3 SiGe process | Enables low-noise (2.4 nV/√Hz) and low-distortion (–84 dBc HD2) performance at reduced supply overhead |
| 0.1-dB flat bandwidth | 300 MHz at G = +2 - ensures amplitude accuracy across wide IF/RF bands without equalization |
| Settling time to 1% | 4.5 ns at G = –2, 2-V step - meets timing budgets for >200-MSPS ADC sampling clocks |
| Input common-mode range | –0.2 V to 4.6 V at 5-V supply - accommodates DC-coupled inputs from 0 V to near-rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Higher quiescent current (20 mA), lower 0.1-dB flat bandwidth (180 MHz), same SOIC-8 package | Less suitable for ultra-low-distortion ADC driving above 100 MHz due to higher HD2 (–75 dBc) | Select when cost sensitivity outweighs SFDR requirements and layout constraints permit larger decoupling |
| ADA4817-1ARZ | Faster settling (2.7 ns to 0.1%), lower input bias current (1.2 µA), but narrower small-signal BW (1 GHz at G = +1) | Better for precision low-current sensor interfaces; insufficient bandwidth for >500-MHz IF applications | Prefer for DC-coupled, low-offset applications where 1-GHz bandwidth suffices and 3-V supply is mandatory |
Compared with LMH6702MA/NOPB and ADA4817-1ARZ, THS4304DRG4 uniquely combines 3-GHz unity-gain bandwidth, 2.4-nV/√Hz noise, and single 5-V operation - making it optimal for RF-sampling ADC drivers where dynamic range and supply simplicity are co-constrained.

FAQ
What is the maximum operating temperature for THS4304DRG4?
The THS4304DRG4 has a maximum continuous operating free-air temperature of 125°C, with junction temperature limited to 125°C for long-term reliability and distortion performance. At 85°C ambient, its power dissipation is rated at 410 mW in the SOIC-8 package, requiring standard PCB thermal relief for sustained operation.
Does THS4304DRG4 support true single-supply operation with rail-to-rail input?
Yes, THS4304DRG4 supports true single-supply operation from 2.7 V to 5 V, with input common-mode range extending from –0.2 V to 4.6 V at 5-V supply - allowing DC-coupled inputs down to 200 mV below ground and up to 400 mV below VS+. However, it is not rail-to-rail input; the input stage requires ≥0.2 V headroom from each rail for linear operation.
Can THS4304DRG4 drive a 50-Ω load directly?
THS4304DRG4 is characterized for 100-Ω loads and can source/sink ≥100 mA, but driving a 50-Ω load directly causes excessive current demand (>100 mA peak) and degrades distortion and settling performance. For 50-Ω systems, use a series 50-Ω resistor at the output or a dedicated 50-Ω line driver stage - as shown in TI's THS4304 evaluation schematics.
What is the recommended feedback resistor value for THS4304DRG4 at G = +2?
Texas Instruments specifies 249 Ω as the recommended feedback resistor for THS4304DRG4 at G = +2 configuration. This value balances output loading, frequency response peaking (~2 dB), and harmonic distortion performance. Using 499 Ω increases peaking to ~5 dB but improves HD2 by ~3 dB; values below 249 Ω reduce peaking but degrade distortion into heavy loads.
Is THS4304DRG4 pin-compatible with other packages in the THS4304 family?
No, THS4304DRG4 (SOIC-8) is not pin-compatible with THS4304DBVT (SOT-23-5) or THS4304DGK (MSOP-8). The SOIC-8 variant has two NC pins (5 and 6) and separate VS+ (pin 7) and VS− (pin 3) rails, whereas SOT-23-5 consolidates supply and omits IN+ and IN− isolation. Layout and decoupling must be redesigned for each package.
