Product details
Overview
THS4130CDR from Texas Instruments is a high-speed, low-noise, fully differential input/output amplifier optimized for precision signal conditioning in high-dynamic-range systems. It delivers 170 MHz small-signal bandwidth (±15 V), 51 V/µs slew rate, –102 dBc THD at 250 kHz, and 1.25 nV/√Hz input voltage noise - enabling high-fidelity differential ADC driving in medical ultrasound and instrumentation.
For engineers reviewing the THS4130CDR datasheet, THS4130CDR pinout, THS4130CDR application, or THS4130CDR equivalent, key selection criteria include its active power-down capability (860 µA shutdown current), ±15 V supply support, VOCM-controlled common-mode output, SOIC-8 package compatibility, and differential gain stability across 5 V to 30 V single-supply operation.
Technical Context
The THS4130CDR implements a true fully differential signal path from input to output using TI's high-voltage complementary bipolar process, enabling 95 dB CMRR at 800 kHz and inherent rejection of even-order harmonics. Its internal VCM error amplifier actively regulates output common-mode voltage via the VOCM pin, supporting precise level-shifting for ADC interface alignment.
It operates with dual supplies up to ±15 V or single supplies from 5 V to 30 V, and features an active-low power-down pin (PD) that places outputs in high-impedance state (<1 MΩ) while reducing quiescent current to 0.86 mA - critical for power-gated signal chains in portable and battery-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 170 MHz at ±15 V supply - enables wideband signal acquisition without phase distortion in RF front-ends and ultrasound beamforming. |
| Slew rate | 51 V/µs - supports fast transient response for high-amplitude, high-frequency signals like pulsed Doppler waveforms. |
| Total harmonic distortion | –102 dBc at 2 VPP, 250 kHz - ensures minimal spectral contamination when driving 14+ bit ADCs in precision data acquisition. |
| Input voltage noise | 1.25 nV/√Hz at 10 kHz - preserves SNR in low-level sensor signal amplification stages before digitization. |
| Power-down current | 0.86 mA at 25°C - allows rapid power gating in multi-channel systems without thermal re-stabilization delays. |
| Common-mode rejection | 95 dB at 800 kHz - rejects coupled noise from shared PCB traces or switching power supplies in mixed-signal boards. |
| Supply range | ±2.5 V to ±15 V dual or 5 V to 30 V single - accommodates legacy industrial rails and modern low-voltage embedded systems. |
Pinout & Package
THS4130CDR is packaged in SOIC-8 (D package), with exposed pad omitted - distinct from HVSSOP-8 (DGN) and VSSOP-8 (DGK) variants. Thermal performance relies on standard SOIC board layout practices; no thermal pad connection required.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VIN+ | Differential input terminal | Accepts positive-phase input signal; paired with VIN− to define differential input voltage (VID ≤ ±1.5 V). |
| PD | Active-low power-down control | Pull to VCC− to disable amplifier; internal 250 kΩ pull-up to VCC+ keeps device active if unconnected. |
| VCC− | Negative supply rail | Supports dual-supply operation down to –15 V; sets PD threshold at VCC− + 1.4 V. |
| VOUT− | Negative differential output | Delivers inverted-phase output; forms differential pair with VOUT+ for balanced transmission to ADC inputs. |
| VIN− | Differential input terminal | Accepts negative-phase input signal; matched impedance and layout with VIN+ essential for balance. |
| VOCM | Output common-mode voltage reference | DC voltage applied here sets midpoint of VOUT+/VOUT− swing; bypass with 0.1 µF capacitor to suppress noise. |
| VCC+ | Positive supply rail | Supports dual-supply operation up to +15 V or single-supply up to +30 V; powers internal bias circuitry. |
| VOUT+ | Positive differential output | Delivers non-inverted-phase output; requires matched trace length and termination to VOUT− for optimal CMRR. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential I/O architecture | Eliminates need for external baluns or transformer coupling; enables direct interface to differential-input ADCs like AFE58JD18. |
| Active power-down mode | Reduces supply current to 0.86 mA while placing outputs in >1 MΩ high-Z state - ideal for time-multiplexed channel architectures. |
| VOCM-controlled output level shift | Allows precise alignment of differential output swing to ADC input range (e.g., 0–2 V or ±1 V) without external resistive dividers. |
| High supply voltage capability | Operates up to ±15 V - provides 30 VPP headroom for high-voltage analog front-ends in ultrasound transducer drivers and industrial sensors. |
| Low 1/f noise corner | 350 Hz corner frequency - maintains low noise integrity in DC-coupled applications such as ECG front-ends and precision weigh scales. |
Applications
| Medical Ultrasound Beamforming | Differential ADC Driver |
|---|---|

IC Role / Device Role / Timing Role: Low-output-impedance driver maintaining filter transfer function integrity despite capacitive loading. Use Value: 51 V/µs slew rate prevents slew-induced distortion in fast-rising filter step responses; 1.25 nV/√Hz noise avoids degrading filter-limited SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4131CDR | No power-down pin; 15.4 µA max input bias current vs. THS4130CDR's 15.4 µA (same spec); identical bandwidth and noise. | Lacks shutdown capability - unsuitable for power-gated multi-channel systems but simpler for always-on designs. | Select THS4131CDR only when power-down functionality is unnecessary and board space allows same SOIC-8 footprint. |
| LMH5401RTVR | Higher 1.8 GHz bandwidth, 3.5 nV/√Hz noise, no VOCM pin; uses VCM pin for fixed 0.95×VCC output offset. | Optimized for RF/IF signal chains above 100 MHz; lacks flexible common-mode control needed for precision ADC interfacing. | Choose LMH5401RTVR for GHz-range applications where THS4130CDR's 170 MHz bandwidth is limiting - but verify VOCM dependency is absent. |
Compared with THS4130CDR, THS4131CDR removes power management overhead at the cost of flexibility, while LMH5401RTVR trades configurability for raw speed - making THS4130CDR the optimal choice for precision, power-aware, medium-bandwidth differential signal chains.

FAQ
What is the maximum supply voltage rating for THS4130CDR?
The THS4130CDR has an absolute maximum supply voltage rating of 33 V across VCC+ and VCC− terminals. For reliable operation, it is specified over a recommended dual-supply range of ±2.5 V to ±15 V or single-supply range of 5 V to 30 V. Exceeding ±15 V or 30 V risks permanent damage per Absolute Maximum Ratings table in the datasheet.
Does THS4130CDR support single-supply operation?
Yes, THS4130CDR supports true single-supply operation from 5 V to 30 V. Its input common-mode range extends from –3.77 V to 4.3 V (at 5 V supply), and VOCM pin allows setting output common-mode voltage anywhere within the supply rails - enabling rail-to-rail compatible interfacing with single-supply ADCs.
How does the PD pin function on THS4130CDR?
The PD pin on THS4130CDR is an active-low power-down control. When pulled below VCC− + 1.4 V (typically to VCC−), the amplifier enters shutdown mode with quiescent current reduced to 0.86 mA and outputs placed in high-impedance state (>1 MΩ). An internal 250 kΩ pull-up to VCC+ keeps the device active if PD is left unconnected.
What is the role of the VOCM pin in THS4130CDR?
The VOCM pin on THS4130CDR sets the DC common-mode voltage of the differential outputs (VOUT+ and VOUT−). Applying a stable voltage here directly defines their midpoint - for example, 2.5 V yields a ±2 V swing around 2.5 V. This eliminates external level-shifting components and ensures optimal matching to ADC input ranges, especially in time-gain-controlled ultrasound receivers.
Which packages are available for THS4130CDR?
THS4130CDR is offered exclusively in the SOIC-8 (D) package, identified by the "D" suffix in the orderable part number (e.g., THS4130CDR). It is not available in VSSOP-8 (DGK) or HVSSOP-8 (DGN) variants - those correspond to THS4130CDGK and THS4130CDGN, respectively, which feature different thermal characteristics and pinouts.
