Product details
Overview
THS2630DGNR from Texas Instruments is a fully differential amplifier (FDA) designed for high-fidelity signal conditioning in precision analog front-ends. It delivers 187 MHz small-signal bandwidth, 75 V/µs slew rate, and –108 dBc THD at 250 kHz with ±15 V supplies - enabling low-noise, high-dynamic-range differential driving in ultrasound receivers and high-speed ADC interfaces.
For engineers reviewing the THS2630DGNR datasheet, THS2630DGNR pinout, THS2630DGNR application, or THS2630DGNR equivalent, this page provides verified package mapping (HVSSOP-8), confirmed FDA functional behavior, validated VOCM control range (–14 V to +13.7 V at ±15 V supply), and real-world distortion vs. frequency performance data per TI SLOSE96A.
Technical Context
The THS2630DGNR implements a true fully differential signal path from input to output using TI's high-voltage complementary bipolar process, supporting supply voltages up to ±17.5 V. Its internal VOCM error amplifier enables precise common-mode output voltage control independent of gain configuration.
It operates in two primary modes: differential-input amplification (with matched RF/RG networks) and single-ended-to-differential conversion (using VOCM to set output common-mode level). Common-mode rejection remains ≥95 dB at 800 kHz, and power-supply rejection exceeds 98 dB - critical for mixed-signal systems with noisy rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 187 MHz at ±15 V supply, G = 1 - supports >100 MSPS ADC sampling with minimal gain roll-off. |
| Slew rate | 75 V/µs - enables clean 2 VPP full-scale step response within 52 ns to 0.01% settling. |
| Total harmonic distortion | –108 dBc at 250 kHz, 2 VPP output, ±15 V supply - ensures sub-0.0001% nonlinear distortion in medical imaging chains. |
| Input voltage noise | 1.1 nV/√Hz at 10 kHz - preserves SNR in low-amplitude sensor signal amplification stages. |
| Common-mode rejection | 95 dB at 800 kHz - rejects board-level switching noise and EMI coupling into differential outputs. |
| Supply voltage range | ±2.5 V to ±17.5 V dual supply or 5 V to 35 V single supply - accommodates legacy ±15 V systems and modern low-voltage designs. |
| Output swing | ±13.4 V into 1 kΩ at ±15 V supply - provides >26.8 VPP headroom for wide-dynamic-range applications. |
Pinout & Package
HVSSOP-8 (DGN) package: 3 mm × 4.9 mm body with exposed thermal pad on underside; requires solder connection to PCB copper plane for thermal management per TI SLMA002/SLMA004 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN− (1) | Negative differential input | Accepts inverted-phase input signal; forms balanced pair with VIN+ for common-mode noise cancellation. |
| VIN+ (8) | Positive differential input | Accepts non-inverted-phase input signal; matched impedance and layout critical for output balance. |
| VOCM (2) | Output common-mode control | DC voltage applied here sets average of VOUT+ and VOUT−; floating defaults to midsupply (±15 V → 0 V). |
| VCC+ (3) | Positive supply rail | Supports up to +17.5 V; internal bias generation and output stage sourcing originate here. |
| VCC− (6) | Negative supply rail | Supports down to –17.5 V; sinks output stage current and defines lower VOCM limit (–14 V at ±15 V). |
| VOUT+ (4) | Positive differential output | Delivers amplified, phase-aligned signal; must be terminated symmetrically to preserve balance. |
| VOUT− (5) | Negative differential output | Delivers amplified, inverted-phase signal; mismatched loading degrades CMRR and HD2 performance. |
| PD (7) | Power-down enable (THS2630S only) | Not connected on THS2630DGNR - this variant lacks active shutdown functionality per pin function table. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential I/O architecture | Eliminates need for external baluns or transformers in ADC driver stages, reducing BOM count and layout area. |
| 1.1 nV/√Hz input voltage noise | Enables detection of µV-level signals without degradation in high-gain ultrasound receive paths. |
| 95 dB CMRR at 800 kHz | Maintains signal integrity in environments with fast-switching digital noise (e.g., FPGA-based acquisition systems). |
| ±17.5 V maximum supply | Supports legacy industrial instrumentation rails while delivering >26 VPP output swing into 1 kΩ. |
| Matched internal 10 kΩ output resistors | Reduces sensitivity to external resistor tolerance; enables <0.1% output balance error with 1% RF/RG. |
Applications
| Ultrasound Receiver Front-End | Differential ADC Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4561DR | Lower noise (0.95 nV/√Hz), lower bandwidth (1.1 GHz GBW), no VOCM pin - uses internal feedback for fixed common-mode. | Better for ultra-low-noise, high-GHz applications where VOCM flexibility is unnecessary; not suitable when output common-mode must track an external reference. | Select THS4561DR when maximizing SNR above 10 MHz is critical and VOCM control is not required. |
| LMH5401RTVT | Higher bandwidth (18 GHz GBW), higher supply current (32 mA), supports only single-ended inputs - no differential input capability. | Targeted at RF/IF signal chains (e.g., direct-conversion receivers); unsuitable for sensor-level signal conditioning due to input structure and power consumption. | Select LMH5401RTVT only for GHz-range single-ended-to-differential conversion with minimal latency. |
Compared with THS2630DGNR, THS4561DR trades VOCM programmability for lower noise and higher speed, while LMH5401RTVT sacrifices differential input support and efficiency for extreme RF bandwidth - making THS2630DGNR the optimal choice for precision, flexible, medium-bandwidth FDA applications.

FAQ
What is the supply voltage range supported by the THS2630DGNR?
The THS2630DGNR supports dual supplies from ±2.5 V to ±17.5 V or single supplies from 5 V to 35 V. At ±15 V, it delivers ±13.4 V output swing into 1 kΩ, and its quiescent current is 11–13.2 mA. The device is characterized for operation from –40°C to +85°C ambient temperature.
Does the THS2630DGNR include power-down functionality?
No - the THS2630DGNR does not include a power-down pin. Only the THS2630S variant features an active-low PD pin. The THS2630DGNR is always active when powered; shutdown current data (0.77–0.92 mA) applies exclusively to the THS2630S part number.
How is the output common-mode voltage controlled on the THS2630DGNR?
The THS2630DGNR uses the VOCM pin (Pin 2) to set output common-mode voltage. Applying a low-impedance voltage source to VOCM directly defines the average of VOUT+ and VOUT−. If left floating, VOCM defaults to midsupply (e.g., 0 V for ±15 V supplies), with a typical offset of ±0.65 mV.
What is the recommended resistor tolerance for optimal THS2630DGNR performance?
TI recommends 1% or better tolerance for feedback (RF) and gain-setting (RG) resistors to minimize output balance error, maintain CMRR >95 dB, and preserve HD2 performance. Table 8-1 in the datasheet specifies exact values: e.g., 390 Ω for both RF and RG at G = 1.
Can the THS2630DGNR drive capacitive loads, and if so, what is the recommended approach?
Yes - but for capacitive loads >10 pF, TI recommends adding a 20 Ω series resistor at each output (VOUT+, VOUT−) to maintain stability. This isolates the amplifier from load capacitance and prevents high-frequency ringing, especially critical in 50 Ω transmission-line applications.
