Product details
Overview
THS7001CPWPR from Texas Instruments is a single-channel, high-speed programmable-gain amplifier (PGA) with integrated low-noise preamplifier stage, designed for precision 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 robust interfacing to ADCs in medical imaging front-ends.
For engineers reviewing the THS7001CPWPR datasheet, THS7001CPWPR pinout, THS7001CPWPR application, or THS7001CPWPR equivalent, this page provides verified circuit role, validated pin functions, confirmed thermal package behavior, real-world gain accuracy across all 8 settings, and direct alternatives for analog signal chain redesign where programmable gain, low-noise amplification, and output clamping are required.
Technical Context
The THS7001CPWPR implements a two-stage architecture: a voltage-feedback preamplifier (Gmin = −1 or 2, 100 MHz BW, accessible output for external filtering) followed by an inverting digital PGA with TTL-compatible 3-bit gain control (G2/G1/G0). The preamp output connects directly to the PGA input, enabling cascaded gain staging without external interconnect.
Both stages support independent shutdown via TTL-level SHDN pins, and the PGA includes dedicated VH/VL clamp terminals that limit output swing to prevent ADC saturation. The device operates on split supplies up to ±16 V, with gain accuracy maintained within ±7.5% over temperature and supply variations - critical for calibrated measurement systems.

Pinout & Package
THS7001CPWPR uses a 20-pin PowerPAD™ plastic TSSOP (PWP) package with exposed thermal pad on underside for enhanced heat dissipation. The PowerPAD must be soldered to a PCB thermal plane to maintain junction temperature below 150°C under full load.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Analog ground reference | Common return for preamp and PGA stages; requires low-impedance connection to system ground plane |
| VREFPGA | PGA reference input | Sets common-mode level for PGA output; tied to mid-supply or external bias for level-shifting |
| −VINPGA | Inverting PGA input | Receives preamp output or external signal; configured as inverting gain stage |
| VOUTPre-AMP | Preamplifier output | Accessible node for external RC filtering or gain adjustment before PGA stage |
| −VINPre-Amp | Inverting preamp input | Differential input terminal; used with +VINPre-Amp for balanced signal reception |
| +VINPre-Amp | Non-inverting preamp input | Differential input terminal; paired with −VINPre-Amp for low-noise differential sensing |
| VCC−Pre-Amp | Negative preamp supply | Connects to negative rail; shares supply domain with PGA VCC− but may be decoupled separately |
| VCC+Pre-Amp | Positive preamp supply | Connects to positive rail; shares supply domain with PGA VCC+ but may be decoupled separately |
| G0, G1, G2 | Digital gain control inputs | TTL-compatible 3-bit bus defining one of eight gain states per Table 1 in datasheet |
| SHDN | Shutdown control input | Active-low logic input disabling both preamp and PGA; pulls supply current to ≤1.2 mA total |
| VOUTPGA | PGA output | Final amplified and clamped output; drives ADC input or next stage with 20 Ω typical output impedance |
| VL (CLAMP−) | Negative output clamp | Defines lower clamp threshold; connected to fixed voltage or ground for unidirectional limiting |
| VCC−PGA | Negative PGA supply | Shared with preamp VCC−; must be ≤ preamp supply magnitude per datasheet constraint |
| VCC+PGA | Positive PGA supply | Shared with preamp VCC+; must be ≤ preamp supply magnitude per datasheet constraint |
| VH (CLAMP+) | Positive output clamp | Defines upper clamp threshold; set independently of VL to create asymmetric clipping windows |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7001IPWPR | Same architecture and pinout, but rated for −40°C to +85°C operating range vs. THS7001CPWPR's 0°C to +70°C | Required for extended-temperature industrial or automotive under-hood environments where ambient exceeds 70°C | Select THS7001IPWPR when operating temperature range must exceed 70°C; otherwise THS7001CPWPR is optimal for commercial-grade instrumentation. |
| PGA112AIDGST | Single-supply (2.7–5.5 V), rail-to-rail I/O, 10-bit SPI interface, lower bandwidth (10 MHz), higher gain error (±0.1% FSR) | Targets battery-powered, low-voltage portable instruments; lacks dual-supply flexibility and high-speed clamping | Choose PGA112AIDGST only for space-constrained, low-power, single-supply designs where bandwidth <10 MHz suffices and digital interface is preferred. |
Compared with THS7001IPWPR, the THS7001CPWPR trades extended temperature capability for lower cost and qualification overhead in commercial instrumentation; versus PGA112AIDGST, it offers superior speed, noise, and dual-supply robustness at the expense of SPI control and rail-to-rail convenience.

FAQ
What is the maximum supply voltage rating for THS7001CPWPR?
The THS7001CPWPR has an absolute maximum supply voltage rating of ±16.5 V per rail. However, the recommended operating range is ±4.5 V to ±16 V. Exceeding ±16.5 V risks permanent damage. Operation at ±16 V is fully supported and commonly used to maximize output swing and dynamic range in high-voltage data acquisition systems.
Does THS7001CPWPR support true differential input operation?
Yes, THS7001CPWPR supports true differential input operation at the preamplifier stage via +VINPre-Amp and −VINPre-Amp pins. The preamp is a voltage-feedback amplifier with minimum gain of −1 or +2, enabling balanced signal acquisition with high common-mode rejection (80 dB typical at 25°C). The PGA stage accepts the preamp's single-ended output.
How does the output clamping function work on THS7001CPWPR?
The THS7001CPWPR provides independent positive (VH) and negative (VL) clamp terminals. When the PGA output attempts to exceed VH or fall below VL, internal circuitry limits the voltage to those thresholds with ±50 mV accuracy at ±5 V supply. This protects downstream ADCs from saturation and reduces recovery time after overdrive events.
What is the gain accuracy specification for THS7001CPWPR across all settings?
The THS7001CPWPR specifies gain accuracy of −7.5% to +7.5% over temperature and supply for all eight gain settings (−22 dB to +20 dB). At room temperature, accuracy tightens to −7.5% to 0%, ensuring predictable scaling in calibrated measurement systems without per-gain calibration.
Can THS7001CPWPR be used with single-supply operation?
No, THS7001CPWPR requires dual ± supplies (e.g., ±5 V, ±12 V, or ±15 V) and is not specified for single-supply use. Its internal architecture relies on symmetric rail operation for proper biasing of both preamp and PGA stages. Attempting single-supply operation will result in undefined behavior or failure to meet datasheet specifications.
