Product details
Overview
THS4130IDGN from Texas Instruments is a fully differential input/output amplifier optimized for high-speed, low-noise signal conditioning in precision analog front-ends. It delivers 170 MHz small-signal bandwidth, 51 V/µs slew rate, and –102 dBc THD at 250 kHz with ±15 V supplies, operating across –40°C to +85°C. Its integrated power-down pin (PD), 1.25 nV/√Hz input voltage noise, and HVSSOP-8 PowerPAD™ package make it suitable for ultrasound receiver chains and high-resolution ADC driver applications.
For engineers reviewing the THS4130IDGN datasheet, THS4130IDGN pinout, THS4130IDGN application, or THS4130IDGN equivalent, key selection criteria include differential output impedance control, VOCM pin flexibility for common-mode level setting, shutdown current of 860 µA, thermal performance enabled by the exposed thermal pad, and compatibility with ±2.5 V to ±15 V dual-supply or 5 V to 30 V single-supply operation.
Technical Context
The THS4130IDGN 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 architecture includes matched internal 10 kΩ resistors tied to the VOCM error amplifier, supporting precise common-mode output control independent of gain configuration.
Power-down functionality is implemented via an active-low PD pin referenced to VCC–, with threshold ~1.4 V above VCC–; pulling PD to VCC– places outputs in high-impedance state (>1 MΩ). The device maintains stable operation with capacitive loads ≥10 pF only when series output isolation resistors (e.g., 20 Ω) are used due to internal compensation optimized for bandwidth and slew rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Total harmonic distortion | –102 dBc at 2 VPP, 250 kHz, ±15 V - ensures minimal spectral contamination in high-fidelity ADC driver stages |
| Input voltage noise | 1.25 nV/√Hz at 10 kHz - critical for preserving SNR in low-amplitude sensor interfaces like ultrasound transducer preamps |
| Quiescent current (shutdown) | 860 µA - allows low-power standby mode in battery-sensitive portable diagnostic equipment |
| Common-mode rejection ratio | 95 dB at 800 kHz - suppresses coupled EMI and ground bounce in mixed-signal PCB layouts |

Pinout & Package
HVSSOP-8 PowerPAD™ package with exposed thermal pad on underside; requires connection to large copper plane for optimal thermal dissipation (RθJB = 30.0 °C/W). Thermal pad is electrically isolated and may be connected to any pin or ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+ | Differential input (non-inverting) | Accepts positive half of fully differential or single-ended input signal; high-impedance node (215 MΩ common-mode RIN) |
| PD | Active-low power-down control | Pulling to VCC– disables amplifier and places outputs in >1 MΩ high-Z state; internal 250 kΩ pull-up to VCC+ keeps device active if floating |
| VCC– | Negative supply rail | Supports dual-supply operation down to –15 V; absolute max rating is 33 V total supply swing (VCC+ to VCC–) |

| VIN– | Differential input (inverting) | Accepts negative half of differential input or serves as reference for single-ended configuration; matched to VIN+ for balance |
| VOCM | Output common-mode voltage setpoint | Directly programs DC offset of differential outputs; bypass with 0.1 µF capacitor to minimize noise coupling into feedback network |
| VCC+ | Positive supply rail | Supports dual-supply operation up to +15 V; PSRR of 98 dB (dc) rejects supply ripple from sensitive analog signal paths |
| VOUT+ | Positive differential output | Delivers non-inverted half of differential output pair; output swing reaches ±11.2 V (min) into 1 kΩ load at ±15 V supply |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4561IRGET | Lower noise (0.89 nV/√Hz), no power-down pin, VSSOP-16 package, 1.2 GHz GBW | Better suited for RF/IF signal chains requiring ultra-low noise and higher bandwidth; lacks shutdown for power-constrained systems | Select THS4561IRGET when maximizing SNR in high-frequency (>100 MHz) applications outweighs need for power management |
| LMH5401RTVT | Higher slew rate (8000 V/µs), 1.2 GHz bandwidth, no VOCM pin, fixed-gain options, WQFN-20 | Optimized for high-speed communications (e.g., DOCSIS, radar); requires external level-shifting circuitry for VOCM-dependent ADC interfaces | Choose LMH5401RTVT for extreme speed requirements where common-mode control is handled externally or not needed |
Compared with THS4130IDGN, THS4561IRGET offers superior noise performance but sacrifices power-down capability and thermal efficiency in HVSSOP-8, while LMH5401RTVT delivers order-of-magnitude faster slew rate at the cost of design complexity for VOCM alignment and PCB area due to larger WQFN-20 footprint.

FAQ
What is the maximum supply voltage rating for THS4130IDGN?
The THS4130IDGN has an absolute maximum supply voltage rating of 33 V between VCC+ and VCC–. Recommended operating conditions specify dual-supply operation from ±2.5 V to ±15 V or single-supply operation from 5 V to 30 V. Exceeding ±15 V in normal operation risks violating recommended conditions, though the device can withstand brief transients within the absolute maximum limits without damage.
How does the VOCM pin function in THS4130IDGN?
The VOCM pin in THS4130IDGN sets the DC common-mode voltage of the differential outputs. When driven by a low-impedance source, it directly defines the average of VOUT+ and VOUT–. If left unconnected, it defaults to mid-rail (VCC+ + VCC–)/2. A 0.1 µF bypass capacitor is recommended to reduce noise coupling. This feature enables seamless interfacing with ADCs requiring specific common-mode input ranges without external level-shifting components.
Does THS4130IDGN support single-supply operation?
Yes, THS4130IDGN supports single-supply operation from 5 V to 30 V. In this mode, VCC– is connected to ground and VCC+ receives the positive rail. The device maintains full differential functionality, including VOCM control and power-down, provided input and output signal swings remain within the specified common-mode input and output voltage ranges (e.g., VICM = –3.77 V to 4.3 V at 5 V supply).
What is the purpose of the thermal pad in the THS4130IDGN HVSSOP-8 package?
The exposed thermal pad in the THS4130IDGN HVSSOP-8 package significantly improves thermal performance, achieving RθJB = 30.0 °C/W when soldered to a large copper plane. It is electrically isolated from the die and may be connected to ground, VCC–, or any other potential without risk. Proper thermal pad connection prevents junction temperature exceedance during sustained 65 mA output current, ensuring reliability in continuous-duty applications like ultrasound beamforming.
Can THS4130IDGN drive capacitive loads directly?
No, THS4130IDGN should not drive capacitive loads >10 pF directly due to reduced phase margin from internal compensation optimized for bandwidth and slew rate. For such loads, a series isolation resistor (minimum 20 Ω) must be placed between each output and the load, as shown in TI's application guidance. This preserves stability and prevents high-frequency ringing or oscillation, especially critical in ADC driver and filter interface applications.
