Product details
Overview
THS4501CDGNR from Texas Instruments is a high-performance fully differential amplifier optimized for precision analog signal conditioning in high-speed data acquisition systems. It delivers 370 MHz small-signal bandwidth, –90 dBc third-order intermodulation distortion at 30 MHz, and 2800 V/μs slew rate under ±5 V supply, enabling clean signal amplification ahead of 14-bit ADCs in wireless receiver chains and active filtering applications.
For engineers reviewing the THS4501CDGNR datasheet, THS4501CDGNR pinout, THS4501CDGNR application, or THS4501CDGNR equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases with design-value context, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The THS4501CDGNR implements a fully differential architecture with independent input common-mode range extending to the negative rail (–5.7 V at ±5 V supply) and precise output common-mode voltage control via VOCM terminal. Its high linearity stems from symmetrical internal topology and low-distortion biasing, supporting 14-bit operation through 40 MHz without degradation.
Unlike the THS4500, the THS4501CDGNR omits power-down functionality-confirmed by absence of PD pin function and identical pinout excluding NC on Pin 7. It operates across wide supply ranges (±5 V, +5 V, up to ±7.5 V or +15 V), with input impedance of 10⁷ Ω || 1 pF and closed-loop output impedance of 0.1 Ω at 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 370 MHz at G = +1, ±5 V supply - enables baseband-to-IF amplification without gain peaking in wideband receivers. |
| Third-order IMD | –90 dBc at 30 MHz, 2 VPP output - ensures minimal spectral regrowth when driving high-resolution ADCs in LTE/WiMAX front ends. |
| Slew rate | 2800 V/μs - supports full-scale transient response for 14-bit, 80 MSps ADC interfaces without slewing-induced distortion. |
| OIP3 | 49 dBm at 30 MHz, referenced to 50 Ω - quantifies robust RF linearity for direct-conversion receiver preamplifier stage. |
| Input voltage noise | 7 nV/√Hz above 1 MHz - preserves SNR in low-noise signal chains where thermal noise dominates over quantization noise. |
| Common-mode input range | –5.7 V to +2.6 V at ±5 V supply - allows single-ended sensor inputs referenced to ground while maintaining full dynamic range. |
| Differential output swing | ±7.4 V into 1 kΩ load at +85°C - delivers headroom for driving transformer-coupled or resistive-terminated ADC inputs. |
Pinout & Package
The THS4501CDGNR is housed in an 8-pin MSOP PowerPAD™ package (DGN), featuring exposed thermal pad for enhanced thermal dissipation. The PowerPAD must be soldered to a PCB copper plane per TI SLMA002/SLMA004 guidelines to maintain junction temperature ≤125°C during continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN− | Inverting input | Accepts differential or single-ended input; common-mode range includes negative rail for ground-referenced sources. |
| VIN+ | Non-inverting input | Paired with VIN− for true differential operation; matched input impedance minimizes CMRR degradation. |
| VOCM | Output common-mode control | Programs DC offset of differential outputs (e.g., 2.5 V for ADC reference); bandwidth 180 MHz ensures fast settling. |
| VS+ | Positive supply | Supports ±5 V, +5 V, or up to +15 V single supply; PSRR ≥75 dB maintains gain stability against rail noise. |
| VOUT+ | Positive differential output | Delivers amplified, balanced signal; output balance error –58 dB ensures <0.1% amplitude/phase mismatch into ADC inputs. |
| VS− | Negative supply | Required for dual-supply operation; enables rail-to-rail input common-mode range down to VS−. |
| VOUT− | Negative differential output | Complementary to VOUT+; differential swing ±7.4 V at +85°C supports high-fidelity signal integrity. |
| NC | No connect | Pin 7 is unconnected (not PD)-confirms THS4501 identity versus THS4500 which uses this pin for power-down control. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order harmonics and common-mode noise coupling, improving SFDR by >15 dB vs. single-ended amplifiers in ADC driver applications. |
| Output common-mode control (VOCM) | Enables precise alignment of differential output DC level to ADC reference voltage (e.g., 2.5 V), removing need for AC-coupling capacitors. |
| Wide supply voltage range | Operates from ±5 V to ±7.5 V or +5 V to +15 V, allowing reuse across multiple system voltage domains without redesign. |
| Input common-mode range includes VS− | Accepts ground-referenced sensors or DAC outputs directly, avoiding level-shifting circuitry and associated noise/error sources. |
| High OIP3 (49 dBm) | Supports high-input-power RF stages without compression, critical for wide dynamic range receivers handling strong interferers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4500CDGNR | Includes power-down pin (PD); otherwise identical bandwidth, IMD, and noise performance. | Required where system-level power gating is needed (e.g., battery-powered portable instruments). | Select THS4500CDGNR only if explicit power-down control is required; THS4501CDGNR offers same signal-chain performance with simpler control interface. |
| THS4131IDGNR | Lower bandwidth (150 MHz), higher supply voltage (±15 V), lower noise (1.3 nV/√Hz), no VOCM pin. | Suited for high-voltage, low-frequency precision instrumentation-not for >40 MHz ADC drivers. | Choose THS4131IDGNR for ±15 V systems needing ultra-low noise below 10 MHz; THS4501CDGNR is superior for wideband, VOCM-controlled ADC interfacing. |
Compared with THS4500CDGNR, THS4501CDGNR removes power-down complexity while retaining identical AC/DC specs-ideal for always-on signal chains. Versus THS4131IDGNR, it trades voltage headroom and noise for bandwidth and VOCM flexibility, making it the preferred choice for modern high-speed data converters.

FAQ
What is the maximum operating supply voltage for THS4501CDGNR?
The THS4501CDGNR supports a maximum specified operating voltage of ±7.5 V in dual-supply mode or +15 V in single-supply mode, as confirmed in the Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. At ±5 V, it achieves optimal linearity and bandwidth; increasing supply improves output swing but not small-signal bandwidth.
Does THS4501CDGNR support single-ended input configurations?
Yes, THS4501CDGNR supports single-ended-to-differential conversion, as explicitly stated in its Applications section and validated in typical circuit diagrams. With VIN− grounded or biased and VIN+ driven, the device produces balanced differential outputs controlled by VOCM-enabling direct interface to ADCs without external baluns or transformers.
How does the VOCM pin function in THS4501CDGNR?
The VOCM pin sets the DC common-mode level of both VOUT+ and VOUT− outputs. When driven to 2.5 V, it centers the differential output around 2.5 V, matching standard 14-bit ADC references. Its 180 MHz bandwidth ensures fast settling during dynamic VOCM updates, and its input impedance is 25 kΩ || 1 pF, requiring low-impedance drive for stability.
What is the thermal requirement for THS4501CDGNR's PowerPAD package?
The THS4501CDGNR's MSOP PowerPAD package requires connection of the exposed thermal pad to a PCB copper pour for effective heat dissipation. Per TI SLMA002, failure to do so may cause junction temperature to exceed +125°C-degrading distortion performance and reliability. Thermal resistance θJA is 58.4°C/W, and recommended layout includes ≥4 thermal vias under the pad.
Is THS4501CDGNR pin-compatible with THS4500CDGNR?
Yes, THS4501CDGNR is pin-compatible with THS4500CDGNR in the DGN package: both share identical 8-pin MSOP layout, with Pin 7 designated NC for THS4501CDGNR and PD for THS4500CDGNR. No PCB changes are required when substituting THS4501CDGNR for THS4500CDGNR in non-power-down designs.
