Product details
Overview
THS7001IPWP from Texas Instruments is a single-channel, high-speed programmable-gain amplifier (PGA) with integrated low-noise preamplifier, designed for precision analog signal conditioning in variable-impedance sensor and data acquisition systems. It delivers 1.7 nV/√Hz input voltage noise, 100 MHz preamp bandwidth, −22 dB to +20 dB digitally programmable gain in 6 dB steps, ±4.5 V to ±16 V dual supply operation, and output clamp protection - enabling direct interface with ADCs in medical imaging front-ends.
For engineers reviewing the THS7001IPWP datasheet, THS7001IPWP pinout, THS7001IPWP application, or THS7001IPWP equivalent, this page provides verified functional specifications, thermal-aware PowerPAD® package details, real-world gain accuracy data across temperature, and validated alternatives for signal chain design continuity.
Technical Context
The THS7001IPWP implements a two-stage architecture: a voltage-feedback preamplifier with accessible output for external filtering, followed by an inverting PGA with TTL-compatible 3-bit digital gain control (G2/G1/G0). The preamp operates at minimum gain of −1 or +2 and maintains 100 MHz (−3 dB) bandwidth independent of PGA stage loading.
The PGA provides 70 MHz (−3 dB) bandwidth across its full −22 dB to +20 dB range, 175 V/µs slew rate at ±15 V supplies, and dual-level output clamping (VL/VH) referenced to GND to prevent ADC saturation. Independent shutdown control per channel enables power gating and multiplexing without signal path interruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Preamp Voltage Noise | 1.7 nV/√Hz at 10 kHz - enables high-fidelity amplification of µV-level sensor signals without degrading SNR. |
| Preamp Bandwidth | 100 MHz (−3 dB) at ±15 V - supports wideband applications including ultrasound receive chains and high-speed test equipment. |
| PGA Gain Range | −22 dB to +20 dB in 6 dB steps - eight discrete gain settings allow precise dynamic range adaptation for varying input amplitudes. |
| Output Clamp Accuracy | ±50 mV at ±5 V supply (VH = +2 V, VL = −2 V) - ensures reliable ADC input protection within 0.1% of reference level. |
| Supply Voltage Range | ±4.5 V to ±16 V split supply - accommodates legacy industrial rails and modern high-voltage sensor interfaces without level-shifting. |
| Operating Temperature | −40°C to +85°C (I-suffix) - qualified for automotive cabin electronics, industrial PLC I/O modules, and outdoor instrumentation. |
| Shutdown Enable Time | 1.5 µs - fast wake-up supports burst-mode acquisition and low-duty-cycle power management strategies. |
Pinout & Package
THS7001IPWP uses a 20-pin PowerPAD™ Plastic TSSOP (PWP) package with exposed thermal pad on underside, requiring solder connection to PCB ground plane for thermal dissipation. Pin numbering follows standard top-view orientation per datasheet Figure "THS7001 PWP PACKAGE (TOP VIEW)".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return for both preamp and PGA sections; must be low-impedance and thermally coupled to PowerPAD. |
| VREFPGA | PGA reference input | DC bias point for PGA inverting input; sets common-mode output level and clamp thresholds. |
| −VINPGA | PGA inverting input | Primary signal input to PGA stage; accepts filtered preamp output or external signal. |
| VOUTPre-AMP | Preamplifier output | Accessible node between preamp and PGA - allows insertion of RC filters or gain-setting resistors. |
| −VINPre-Amp | Preamplifier inverting input | Differential input terminal; used with +VINPre-Amp for balanced source interfacing. |
| +VINPre-Amp | Preamplifier non-inverting input | Differential input terminal; paired with −VINPre-Amp for low-noise, high-CMRR signal acquisition. |
| VCC−Pre-Amp | Negative supply for preamp | Separate negative rail pin - decoupling required close to pin to maintain PSRR and stability. |
| VCC+Pre-Amp | Positive supply for preamp | Separate positive rail pin - enables independent preamp supply optimization versus PGA section. |
| G0, G1, G2 | Digital gain control inputs | TTL-compatible 3-bit bus defining one of eight gain states; no pull-ups required. |
| SHDN | Shutdown control | Active-low enable; drives internal circuitry into standby mode with ICC(standby) ≤ 1.2 mA per channel. |
| VOUTPGA | PGA output | Final amplified and clamped output; capable of driving 1 kΩ loads with <0.1% settling to 5 V step. |
| VL (CLAMP−) | Negative output clamp | Lower clamp threshold voltage; limits output swing below GND to protect downstream ADC inputs. |
| VCC−PGA | Negative supply for PGA | Independent negative rail for PGA; must be ≤ preamp supply magnitude per datasheet constraint. |
| VCC+PGA | Positive supply for PGA | Independent positive rail for PGA; same constraint applies as VCC−PGA. |
| VH (CLAMP+) | Positive output clamp | Upper clamp threshold voltage; prevents output overshoot beyond safe ADC input range. |
Key Features
| Feature | Design Value |
|---|---|
| Separate preamp and PGA stages | Enables independent optimization of noise performance (preamp) and dynamic range control (PGA), reducing design iteration in multi-signal-chain systems. |
| Externally filterable preamp output | VOUTPre-AMP pin allows placement of anti-aliasing or bandpass filters before PGA, preserving signal integrity without compromising gain flexibility. |
| Dual-level output clamping (VH/VL) | Hardware-enforced output limits eliminate need for external diode clamps or software-based saturation detection in ADC driver designs. |
| PowerPAD™ thermal package | Exposed thermal pad reduces θJA by >30% vs. standard TSSOP, enabling 3.83 W continuous dissipation at TA = 25°C with proper PCB layout. |
| Gain accuracy ±7.5% over temperature | Validated across −40°C to +85°C at all 8 gain settings - supports calibration-free operation in uncontrolled environments like field-deployed sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7001CPWP | Same architecture and pinout, but rated for 0°C to +70°C only; quiescent current identical, gain accuracy ±7.5% over full range unchanged. | Limited to commercial-temperature environments such as lab instruments or office-based DAQ systems. | Select when operating ambient stays within 0–70°C and cost sensitivity outweighs extended temperature qualification. |
| PGA112AIDGST | Single-supply (2.7–5.5 V), rail-to-rail I/O, lower bandwidth (10 MHz), higher noise (12 nV/√Hz), SPI interface instead of parallel 3-bit control. | Suitable for battery-powered portable sensors, not for high-frequency or bipolar supply systems. | Choose only for low-voltage, low-power, space-constrained designs where bandwidth and noise performance are secondary to integration and supply simplicity. |
Compared with THS7001CPWP, the THS7001IPWP adds −40°C start-up capability and guaranteed performance over industrial temperature extremes, while PGA112AIDGST trades bandwidth and noise for single-supply convenience and digital interface - making THS7001IPWP the sole option for high-fidelity, wide-temperature, bipolar-supply programmable gain.

FAQ
What is the maximum junction temperature specification for THS7001IPWP?
The absolute maximum junction temperature for THS7001IPWP is 150°C. This rating assumes proper thermal management via the PowerPAD™ - the exposed thermal pad must be soldered to a PCB copper plane with ≥4 thermal vias to maintain safe operation at full 3.83 W dissipation. Exceeding this temperature risks permanent parametric shift or failure.
Does THS7001IPWP support true differential input at the preamplifier stage?
Yes, THS7001IPWP supports true differential input at the preamplifier stage via dedicated +VINPre-Amp and −VINPre-Amp pins. Its voltage-feedback architecture achieves 80 dB CMRR at 25°C and maintains >78 dB across −40°C to +85°C, enabling rejection of common-mode noise in noisy industrial or medical environments.
How does gain accuracy vary with temperature for THS7001IPWP?
THS7001IPWP guarantees gain accuracy within ±8.5% over the full −40°C to +85°C range for all eight gain settings. At 25°C, accuracy tightens to ±7.5%, and typical performance shows ±0.3% variation across temperature - confirmed by Figure 33 in the SLOS214C datasheet.
Can THS7001IPWP drive a 50 Ω load directly?
No, THS7001IPWP is not optimized for 50 Ω loads. Its specified output drive is into ≥150 Ω (preamp) or ≥1 kΩ (PGA); driving 50 Ω causes excessive current draw (>100 mA), thermal stress, and bandwidth collapse. For 50 Ω systems, use a dedicated buffer amplifier stage after THS7001IPWP.
Is the THS7001IPWP pinout compatible with THS7002IPWP?
No, THS7001IPWP (single-channel) and THS7002IPWP (dual-channel) have different pinouts despite sharing the same PWP package. THS7002IPWP duplicates preamp/PGA blocks and adds second-channel pins (e.g., G0-A/G0-B), making them electrically and physically incompatible for drop-in replacement.
