Product details
Overview
THS4513RGTTG4 from Texas Instruments is a wideband, fully-differential amplifier optimized for 5-V data acquisition systems. It delivers 2.2 nV/√Hz input voltage noise, –75 dBc HD2 and –86 dBc HD3 at 70 MHz (2-VPP output), 5100 V/μs slew rate, and 2.9 ns 1% settling time - enabling high-fidelity signal conditioning ahead of high-speed ADCs.
For engineers reviewing the THS4513RGTTG4 datasheet, THS4513RGTTG4 pinout, THS4513RGTTG4 application, or THS4513RGTTG4 equivalent, this device is selected for ultra-low distortion, dc-coupled differential drive, and precise output common-mode control in demanding RF, medical imaging, and test equipment signal chains.
Technical Context
The THS4513RGTTG4 employs a fully-differential architecture with independent input and output common-mode control. Its minimum stable gain is 0 dB (unity gain), and it maintains <4-mV differential offset and <5-mV output common-mode offset from set point when CM input is within ±0.5 V of midsupply.
It integrates dedicated CM input terminals (pins 4 & 9) with 1 V/V gain, 250 MHz small-signal bandwidth (5-V supply), and ±40 μA CM input bias current. The amplifier operates from ±1.5 V to ±2.5 V supplies (3–5 V total), drawing 37.7 mA quiescent current and supporting power-down mode (0.65 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 1.6 GHz at G = 0 dB (5-V supply); enables baseband-to-UHF signal amplification without peaking. |
| Slew rate (differential) | 5100 V/μs; supports clean 2-VPP step response with minimal slewing distortion in pulsed applications. |
| HD2 / HD3 @ 70 MHz | –75 dBc / –86 dBc (2-VPP, 200-Ω load); meets stringent linearity requirements for 14+ bit ADC drivers. |
| Input voltage noise | 2.2 nV/√Hz (>10 MHz); preserves SNR in low-amplitude, wideband sensor or IF signal paths. |
| OIP3 @ 70 MHz | 42 dBm (200-kHz tone spacing, 100-Ω load); ensures robust two-tone intermodulation performance in receiver front ends. |
| 1% settling time | 2.9 ns (2-V step); critical for time-interleaved or high-throughput sampling systems requiring fast transient fidelity. |
| Output common-mode control | ±5 mV offset from set voltage; allows precise alignment to ADC input common-mode range without external feedback. |
Pinout & Package
THS4513RGTTG4 is housed in a 16-pin QFN package (RGT) with exposed thermal pad. Pin 1 is NC; pins 5–8 and 13–16 are VS+ and VS− power rails respectively; pins 2 and 11 are VIN− and VIN+; pins 3 and 10 are VOUT+ and VOUT−; pins 4 and 9 are dual CM inputs; pin 12 is PD (active-low power-down).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Must be left unconnected; no routing or grounding required. |
| 2 (VIN−) | Inverting input | Differential input node; referenced to midsupply for optimal CMRR and distortion performance. |
| 3 (VOUT+) | Noninverting output | One side of fully-differential output pair; requires matched termination to maintain balance. |
| 4, 9 (CM) | Common-mode voltage input | Two identical inputs accepting external CM reference; default is 0 V (midsupply) when open. |
| 5–8 (VS+) | Positive supply rail | Four parallel pins reduce IR drop and improve PSRR; connect directly to low-impedance 2.5-V plane. |
| 10 (VOUT−) | Inverting output | Complementary output to VOUT+; differential swing up to 5.6 VPP (5-V supply). |
| 11 (VIN+) | Noninverting input | Primary single-ended or differential input node; supports centered CM range of 1.1 V to 3.9 V (5-V supply). |
| 12 (PD) | Power-down enable | Active-low logic input; drives quiescent current from 37.7 mA to 0.65 mA with 55 ns turn-on delay. |
| 13–16 (VS−) | Negative supply rail | Four parallel pins for return path; must be connected to low-inductance –2.5-V plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully-differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4511RGTT | Same RGT package; wider input CM range (–0.3 V to 2.3 V vs. 1.1 V to 3.9 V), but higher 3.3-nV/√Hz noise at 10 MHz. | Better suited for single-supply 3.3-V systems with low-input-voltage sources; less ideal for 5-V ADCs requiring high CM headroom. | Select THS4511RGTT only if input signal CM falls below 1.1 V and supply is ≤3.3 V; otherwise THS4513RGTTG4 offers superior noise and CM flexibility. |
| LMH5401RTVT | Higher 10-GHz GBW, 10.5-V/μs slew rate, but consumes 65 mA and lacks integrated CM control - requires external feedback network. | Targeted at >1-GHz RF applications (e.g., mmWave test); not optimized for dc-coupled precision ADC driving. | Choose LMH5401RTVT for >3-GHz small-signal bandwidth needs; THS4513RGTTG4 remains preferred for 5-V, low-noise, dc-coupled ADC interface. |
Compared with THS4511RGTT and LMH5401RTVT, the THS4513RGTTG4 uniquely balances ultra-low distortion (–86 dBc HD3), integrated output common-mode control, and 5-V operation - making it the most direct solution for high-resolution, dc-coupled data acquisition where layout simplicity and power efficiency matter.

FAQ
What is the minimum stable gain for THS4513RGTTG4?
The THS4513RGTTG4 is stable at a minimum gain of 0 dB (unity gain). This is explicitly specified in the datasheet and verified across temperature and supply conditions. Unlike many high-speed amplifiers requiring ≥6 dB gain for stability, the THS4513RGTTG4 supports unity-gain configurations without compensation, simplifying use as a buffer or level shifter in differential signal paths.
Does THS4513RGTTG4 support true dc-coupled operation to ADCs?
Yes. The THS4513RGTTG4 features an integrated output common-mode control circuit that maintains output CM voltage within ±5 mV of the set point (e.g., 2.5 V for 5-V supply), even under large-signal transients. This enables direct dc-coupling to ADCs like the ADS54J60 or AD9467 without AC-coupling capacitors or external CM feedback networks - preserving low-frequency fidelity and reducing board area.
What is the power-down behavior of THS4513RGTTG4?
When the PD pin (pin 12) is pulled low, THS4513RGTTG4 enters power-down mode, reducing quiescent current from 37.7 mA to 0.65 mA. Turn-on delay is 55 ns (measured to output stabilization), and turn-off delay is 10 μs. Input bias current drops to 100 μA, and the amplifier outputs enter high-impedance state - allowing safe multiplexing or standby in multi-channel systems.
How does THS4513RGTTG4 handle common-mode input range on a 5-V supply?
On a 5-V supply (±2.5 V), the THS4513RGTTG4 supports a common-mode input range of 1.1 V to 3.9 V - centered around midsupply (2.5 V) with 1.4-V headroom above and below. This range accommodates typical single-ended sources referenced to 2.5 V and avoids clipping in high-gain stages, unlike alternatives with narrower CM ranges such as the THS4509 (1.1 V to 3.9 V, but only at ≥6 dB gain).
Can THS4513RGTTG4 drive a 200-Ω differential load at full swing?
Yes. The THS4513RGTTG4 delivers up to 5.6 VPP differential output swing into a 200-Ω load with 5-V supply, and sustains –86 dBc HD3 at 70 MHz under those conditions. Its output stage provides 96 mA differential current drive capability, ensuring robust loading margin and minimal distortion degradation even with PCB trace impedance mismatches or connector parasitics.
