Product details
Overview
THS7002CPWP from Texas Instruments is a dual-channel, high-speed programmable-gain amplifier (PGA) with integrated low-noise preamplifier stages per channel, ±4.5 V to ±16 V split-supply operation, 100 MHz preamp bandwidth, and −22 dB to +20 dB digitally programmable gain range in 6 dB steps-used in precision analog front-ends for medical imaging, test equipment, and high-fidelity data acquisition systems.
For engineers reviewing the THS7002CPWP datasheet, THS7002CPWP pinout, THS7002CPWP application, or THS7002CPWP equivalent, this page delivers verified specifications, dual-channel PGA/preamp architecture details, PowerPAD™ thermal package constraints, shutdown timing behavior, and real-world clamping performance at ±5 V and ±15 V supplies.
Technical Context
The THS7002CPWP implements two independent signal chains, each comprising a voltage-feedback preamplifier (Gmin = −1 or 2, 1.7 nV/√Hz input noise, 100 MHz −3 dB bandwidth) followed by an inverting digital PGA with three TTL-compatible gain control bits (G2/G1/G0). The preamp output is externally accessible to support inline filtering before PGA input.
Each PGA provides output clamp protection via shared VH/VL terminals, supports ±4.5 V to ±16 V supplies (PGA supply ≤ preamp supply), and delivers 175 V/µs slew rate at ±15 V with 70 MHz −3 dB bandwidth maintained across all eight gain settings. Independent SHDN−A/SHDN−B pins enable per-channel power-down with 1.5 µs enable time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Preamp Bandwidth | 100 MHz (−3 dB) at G = 2, ±15 V - enables wideband sensor signal conditioning without external compensation. |
| PGA Gain Range | −22 dB to +20 dB in 6 dB steps - eight discrete levels controlled by G2/G1/G0, supporting dynamic range adaptation in digitizer front-ends. |
| Input Voltage Noise | 1.7 nV/√Hz (preamp, 10 kHz) - critical for preserving SNR when amplifying microvolt-level transducer outputs. |
| Output Slew Rate | 175 V/µs (PGA, ±15 V) - ensures faithful reproduction of fast transient signals up to ~2.8 MHz full-power bandwidth. |
| Supply Range | ±4.5 V to ±16 V split supply - accommodates legacy industrial rails and high-dynamic-range ADC interfaces. |
| Clamp Accuracy | ±80 mV (±5 V supply, VH/VL = ±2 V) - limits overvoltage stress on downstream ADC inputs during signal overload. |
| Shutdown Current | 0.8 mA per channel (PGA + preamp disabled, ±15 V) - reduces system standby power in multiplexed multi-channel systems. |
Pinout & Package
THS7002CPWP uses a 28-pin PowerPAD™ Plastic TSSOP (PWP) package with exposed thermal pad on underside requiring PCB thermal plane connection. Pin numbering follows standard top-view orientation as defined in Figure 1 of SLOS214C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | GND-A / GND-B | Separate analog ground returns for Channel A and B - minimize crosstalk in dual-channel layout. |
| 2, 13 | PGA-A REF / PGA-B REF | Reference input for PGA stage - sets common-mode level; must be decoupled to local ground. |
| 3, 12 | PGA-A IN− / PGA-B IN− | Inverting input of PGA - accepts filtered preamp output; high-impedance node sensitive to layout parasitics. |
| 4, 11 | PREAMP OUT A / PREAMP OUT B | Accessible preamp output - allows insertion of RC filter between preamp and PGA for anti-aliasing. |
| 5, 10 | PREAMP-A IN− / PREAMP-B IN− | Inverting input of preamp - differential pair input; matched trace routing required for CMRR preservation. |
| 6, 9 | PREAMP-A IN+ / PREAMP-B IN+ | Non-inverting input of preamp - primary signal entry point; low input bias current (≤6 µA) eases sensor interfacing. |
| 7, 16 | PREAMP VCC− / PREAMP VCC+ | Split supply for preamp stage - must be independently decoupled; minimum ±4.5 V required. |
| 8, 15 | PGA VCC− / PGA VCC+ | Split supply for PGA stage - must be ≤ preamp supply voltage; shared decoupling not recommended. |
| 17–19 | G0-A, G1-A, G2-A | Digital gain control bits for Channel A - TTL-compatible; drive directly from FPGA or microcontroller GPIO. |
| 20, 27 | SHDN−A / SHDN−B | Active-low shutdown enable for Channel A/B - pulls internal bias currents to zero; 0.3 V max logic low. |
| 21, 26 | PGA-A OUT / PGA-B OUT | Final amplified output - drives 150 Ω loads; includes internal clamp diodes to VH/VL rails. |
| 22, 25 | CLAMP− (VL) / CLAMP+ (VH) | Shared clamp reference terminals - connect to fixed voltages (e.g., ±2 V or ±10 V) to define output swing limits. |
Key Features
| Feature | Design Value |
|---|---|
| Separate preamp + PGA architecture | Enables independent optimization: ultra-low-noise preamp (1.7 nV/√Hz) precedes high-slew-rate PGA (175 V/µs), avoiding noise/gain trade-offs. |
| Externally accessible preamp output | Permits placement of passive RC filters between preamp and PGA - essential for anti-aliasing without degrading preamp stability. |
| Dual independent shutdown controls | SHDN−A/SHDN−B allow per-channel power gating - reduces idle current by >90% per channel and supports time-division multiplexing. |
| Output clamp protection (VH/VL) | Prevents PGA output from exceeding user-defined voltage rails - protects downstream ADC inputs from latch-up or damage during overrange events. |
| Gain accuracy across temperature | ±8.5% max error over −40°C to +85°C - ensures consistent signal scaling in industrial environments without recalibration. |
| PowerPAD™ thermal package | 28-pin TSSOP with exposed die paddle - requires soldered thermal pad to inner-layer copper pour to maintain TJ < 150°C at full load. |
Applications
| Medical Ultrasound Front-End | Automated Test Equipment (ATE) |

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 | Single-channel version with identical preamp/PGA specs, pinout, and PowerPAD package - shares same 28-pin PWP footprint but lacks second channel. | Used where only one signal path is needed; eliminates inter-channel crosstalk concerns but doubles board area for dual-path designs. | Select THS7001CPWP when system requires only one programmable gain channel and board space permits single-device placement per path. |
| PGA112AIDGST | Single-supply (2.7–5.5 V), rail-to-rail I/O, 10-bit SPI interface, lower bandwidth (10 MHz), higher noise (12 nV/√Hz); no separate preamp stage or VH/VL clamping. | Targeted at battery-powered, low-voltage embedded systems - unsuitable for ±15 V industrial or video applications requiring high slew rate or clamping. | Choose PGA112AIDGST only for low-power, single-supply portable instrumentation where ±16 V operation and 175 V/µs slew are unnecessary. |
Compared with THS7001CPWP, the THS7002CPWP delivers true dual-channel integration without layout duplication, while PGA112AIDGST trades bandwidth, noise, and supply flexibility for digital interface simplicity and ultra-low quiescent current - making it incompatible for high-fidelity, wide-supply analog front-ends.

FAQ
What is the maximum operating temperature range for the THS7002CPWP?
The THS7002CPWP is rated for operation from 0°C to +70°C (C-suffix). This commercial-grade temperature range is validated per the absolute maximum ratings and recommended operating conditions in the SLOS214C datasheet. For extended temperature applications, the THS7002IPWP variant supports −40°C to +85°C.
Does the THS7002CPWP require external passive components to operate?
Yes, the THS7002CPWP requires external decoupling capacitors on all supply pins (PREAMP VCC± and PGA VCC±), pull-up/pull-down resistors on G0/G1/G2 control lines if driven by open-drain sources, and proper termination for the VH/VL clamp references. The preamp output is also intended for optional RC filtering before PGA input - no internal compensation is provided.
How does the THS7002CPWP handle overvoltage conditions at its output?
The THS7002CPWP provides active output clamping via dedicated VH (positive clamp) and VL (negative clamp) terminals. When configured with external voltage references (e.g., ±2 V or ±10 V), the PGA output is limited to those rails with ±80 mV accuracy at ±5 V supply. This protects downstream ADCs from overvoltage damage without requiring external diodes or limiting resistors.
Can the preamp and PGA stages of the THS7002CPWP be used independently?
Yes - the preamp output (PREAMP OUT A/B) is fully accessible and can be used as a standalone low-noise amplifier (G = −1 or 2, 100 MHz BW, 1.7 nV/√Hz). The PGA stage may also be bypassed by grounding its inverting input and driving the reference terminal, though full functionality requires both stages as a cascaded signal chain per channel.
What thermal design considerations apply to the THS7002CPWP PowerPAD package?
The THS7002CPWP uses a PowerPAD™ TSSOP package requiring the exposed thermal pad to be soldered to a dedicated PCB copper pour connected to internal ground or thermal plane. Without this connection, junction temperature exceeds 150°C under load, risking permanent damage. Thermal resistance (θJA) drops from 45°C/W (no pad) to ~30°C/W (with 1-in² 2-oz copper), as specified in the Thermal Information section of SLOS214C.
