Product details
Overview
THS4504DGNR from Texas Instruments is a wideband, low-distortion fully differential amplifier optimized for high-fidelity signal conditioning in ADC driver and RF receiver chain applications. It delivers 260 MHz small-signal bandwidth, –73 dBc third-order intermodulation distortion at 30 MHz, and 1800 V/µs slew rate under ±5 V supply, enabling precise 12-bit, 80 MSps data acquisition systems.
For engineers reviewing the THS4504DGNR datasheet, THS4504DGNR pinout, THS4504DGNR application, or THS4504DGNR equivalent, key selection criteria include power-down functionality, VOCM-controlled common-mode output setting, input common-mode range extending to the negative rail, and MSOP-8 PowerPAD™ thermal performance in space-constrained analog front-ends.
Technical Context
The THS4504DGNR implements a fully differential architecture with independent input and output common-mode control paths. Its dual-loop design separates differential gain setting (via external resistors) from output common-mode voltage regulation (via VOCM pin), supporting both single-ended-to-differential conversion and active filtering of high-frequency signals.
It features an integrated power-down circuit activated by a logic-level PD pin, reducing quiescent current to ≤1.2 mA while maintaining high-impedance outputs. The device operates across ±5 V, ±7.5 V, 5 V, or 15 V supplies, with input common-mode range spanning –5.7 V to +2.6 V (±5 V supply) and output swing up to ±7.4 V into 1 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 260 MHz at G = 1 (±5 V): enables baseband and IF signal amplification up to UHF without gain peaking. |
| Slew rate | 1800 V/µs (±5 V): supports full-scale transient response for 12-bit, 80 MSps ADC interfaces without slewing-induced distortion. |
| IMD3 @ 30 MHz | –73 dBc (200 kHz tone spacing): ensures minimal spectral regrowth in wireless receiver I/Q paths. |
| OIP3 | 29 dBm (±5 V, 30 MHz): provides robust linearity for high dynamic range signal chains before digitization. |
| Input voltage noise | 8 nV/√Hz (>1 MHz): contributes <0.5 LSB noise floor in 12-bit systems with typical source impedances. |
| Power-down current | ≤1200 µA (max, ±5 V): reduces system standby power while preserving fast 1 µs turn-on/turn-off timing. |
| Common-mode input range | –5.7 V to +2.6 V (±5 V): allows direct interfacing with bipolar sensors or DAC outputs without level-shifting. |
Pinout & Package
THS4504DGNR is housed in an 8-pin MSOP package with exposed PowerPAD™ thermal pad (DGN suffix), offering enhanced thermal dissipation (θJA = 58.4°C/W) and improved ac performance versus SOIC-8. The PowerPAD is electrically isolated and must be soldered to PCB ground plane for optimal junction temperature control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN− | Inverting input | Differential input node; accepts signal referenced to system ground or negative rail. |
| VIN+ | Non-inverting input | Differential input node; used with VIN− for balanced signal reception or single-ended input with resistor termination. |
| VOCM | Output common-mode control | DC voltage input setting output common-mode level (e.g., 2.5 V for ADC reference); high-impedance, 25 kΩ || 1 pF. |
| VS+ | Positive supply | Accepts +5 V, +12 V, or +15 V; internal biasing stable across full specified range. |
| VS− | Negative supply | Accepts –5 V, –12 V, or –15 V; supports rail-to-rail input common-mode down to VS−. |
| VOUT+ | Positive differential output | Drives one side of differential load (e.g., ADC inputs); maintains balance within –65 dB up to 100 kHz. |
| VOUT− | Negative differential output | Complementary output node; paired with VOUT+ for fully differential signaling and common-mode rejection. |
| PD | Power-down enable | Active-low control: < –4.3 V disables (high-Z outputs), > –2.9 V enables; default ON if floating. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order harmonics and improves PSRR/CMRR over single-ended amplifiers in mixed-signal systems. |
| Output common-mode voltage control (VOCM) | Enables precise matching to ADC reference voltage (e.g., 2.5 V or 1.25 V) without external resistive dividers. |
| Power-down capability | Reduces quiescent current from 25 mA to ≤1.2 mA, enabling dynamic power management in battery-powered receivers. |
| Wide supply range support | Operates from ±5 V to ±7.5 V or single 5 V to 15 V, simplifying integration across legacy and new designs. |
| Input common-mode range includes VS− | Allows direct connection to ground-referenced sources or negative-biased transducers without level-shifting circuitry. |
Applications
| Wireless Communication Receiver Chains | High-Speed Data Acquisition Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4505DGNR | No power-down pin; otherwise identical AC/DC specs, pinout, and VOCM function. | Preferred where continuous operation is required and power gating adds complexity. | Select THS4505DGNR when system-level power sequencing eliminates need for per-device shutdown control. |
| THS4509RGTR | Higher bandwidth (800 MHz), lower noise (4.3 nV/√Hz), but no VOCM pin; requires external common-mode bias network. | Better suited for >100 MSps ADC drivers where linearity at >100 MHz is critical. | Choose THS4509RGTR only when VOCM control is unnecessary and bandwidth >500 MHz is mandatory. |
Compared with THS4505DGNR, THS4504DGNR adds power-down control at minor cost in layout area; compared with THS4509RGTR, it trades bandwidth for integrated VOCM flexibility and lower design risk in 12-bit, 80 MSps systems.

FAQ
What is the maximum operating supply voltage for THS4504DGNR?
The absolute maximum supply voltage for THS4504DGNR is ±7.5 V for dual-supply operation or 15 V for single-supply use, as specified in the Absolute Maximum Ratings table. Continuous operation above these limits risks permanent damage. For reliable long-term performance, TI recommends staying within the Recommended Operating Conditions of ±5 V to ±7.5 V (dual) or 4.5 V to 15 V (single), where all electrical characteristics are guaranteed.
Does THS4504DGNR require external compensation components?
No, THS4504DGNR is internally compensated and stable for unity-gain (G = +1) configurations with standard feedback networks (e.g., RF = RG = 499 Ω). External compensation is not needed for basic operation, though careful PCB layout-especially grounding the PowerPAD™ and minimizing parasitic capacitance at VOCM-is essential to maintain specified bandwidth and distortion performance.
How does the VOCM pin function in THS4504DGNR?
The VOCM pin sets the DC common-mode voltage of the differential outputs (VOUT+ and VOUT−). When driven with a stable voltage (e.g., 2.5 V), it forces the average of VOUT+ and VOUT− to match that value. This enables seamless interfacing with ADCs having specific reference voltages. VOCM has 25 kΩ input impedance and supports 1.3 V to 3.7 V input range under 5 V supply, with <1 mV offset error.
What is the power-down behavior of THS4504DGNR?
When the PD pin is pulled below –4.3 V (dual supply) or 0.7 V (single 5 V), THS4504DGNR enters power-down mode: quiescent current drops to ≤1200 µA, and both outputs go high-impedance. Turn-off delay is 800 ns; turn-on delay is 1000 ns. If PD is left floating, the device defaults to enabled (ON) state with typical VOCM default voltage near 0 V (±5 V) or 2.5 V (5 V).
Can THS4504DGNR drive a 50 Ω differential load directly?
THS4504DGNR is not rated for continuous 50 Ω differential load driving. Its specified output current drive is 100 mA minimum into 20 Ω (differential), and output voltage swing degrades significantly below 200 Ω. For 50 Ω systems, use a series 25 Ω resistor per output leg to isolate the amplifier and match impedance-this preserves linearity and prevents excessive current draw beyond 130 mA peak capability.
