Product details
Overview
THS7002IPWPR from Texas Instruments is a dual-channel, high-speed programmable-gain amplifier (PGA) with separate low-noise preamplifier stages per channel, ±4.5 V to ±16 V split-supply operation, 100 MHz preamp bandwidth, −22 dB to +20 dB digitally programmable gain range in 6 dB steps, and integrated output clamp protection. It serves signal conditioning in precision data acquisition systems where variable sensor impedance and wide dynamic range are critical.
For engineers reviewing the THS7002IPWPR datasheet, THS7002IPWPR pinout, THS7002IPWPR application, or THS7002IPWPR equivalent, this page delivers verified circuit role, exact pin functions, real-world use cases in video and instrumentation, and two validated alternative PGAs with documented gain accuracy and thermal performance differences.
Technical Context
The THS7002IPWPR integrates two independent signal chains: each comprises a voltage-feedback preamp (Gmin = −1 or 2, 1.7 nV/√Hz input noise, 100 MHz −3 dB bandwidth) followed by a digitally controlled inverting PGA (3-bit TTL-compatible G2/G1/G0 interface, 70 MHz −3 dB bandwidth, 175 V/µs slew rate). The preamp output is externally accessible for filtering or gain adjustment before the PGA stage.
Each channel features independent shutdown control (TTL-compatible SHDN−A/SHDN−B), dual-level output clamping (CLAMP+/CLAMP− shared across channels), and operates over −40°C to +85°C. The PowerPAD™ TSSOP-28 package enables thermal dissipation up to 4.48 W at TA = 25°C, with linear derating to 2.33 W at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Preamp Bandwidth | 100 MHz (−3 dB) at G = 2, ±15 V supply - supports high-fidelity analog front-end sampling of fast transients. |
| PGA Gain Range | −22 dB to +20 dB in 6 dB steps - eight discrete gain settings enable precise dynamic range adaptation without external resistors. |
| Input Voltage Noise | 1.7 nV/√Hz (preamp, f = 10 kHz) - enables detection of µV-level signals in low-amplitude sensor interfaces. |
| Slew Rate | 175 V/µs (PGA, ±15 V supply) - ensures faithful reproduction of fast-rising edges in pulse-based measurement systems. |
| Output Clamp Accuracy | ±80 mV (±5 V supply, full temperature range) - maintains ADC input safety within ±2 V clamp limits without external diodes. |
| Supply Range | ±4.5 V to ±16 V split supply - accommodates legacy industrial rails and high-voltage sensor excitation requirements. |
| Operating Temperature | −40°C to +85°C (I-suffix) - qualified for deployment in automotive engine control units and outdoor instrumentation. |
Pinout & Package
THS7002IPWPR uses a 28-pin PowerPAD™ plastic TSSOP (PWP) package with exposed thermal pad on underside, requiring connection to PCB ground plane for thermal management. Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND-A / GND-B | Analog ground reference (per channel) | Separate ground returns minimize crosstalk between preamp and PGA sections of each channel. |
| PREAMP-A/B IN+ / IN− | Differential preamp inputs | High-impedance (1 MΩ) inputs accept low-level sensor signals; common-mode range extends to ±14 V at ±15 V supply. |
| PREAMP OUT A / B | Preamp output node | Externally accessible for passive RC filtering or gain-setting resistor networks before PGA input. |
| PGA-A/B IN− | Inverting PGA input | Accepts filtered preamp output; input resistance varies from 0.27 kΩ (G = +20 dB) to 3 kΩ (G = −22 dB). |
| G0-A/B, G1-A/B, G2-A/B | Digital gain control bits | TTL-compatible 3-bit parallel interface selects one of eight gain states; no external clock or serial protocol required. |
| SHDN−A / SHDN−B | Channel-specific shutdown enable | Drives internal bias current to <1.2 mA per channel when logic-low; enables power gating in multiplexed systems. |
| CLAMP+ (VH) / CLAMP− (VL) | Shared clamp voltage references | Single pair of terminals sets upper/lower output limits for both PGA channels simultaneously. |
| PGA-A/B OUT | Final amplified output | Capable of driving 150 Ω loads; output clamping prevents saturation-induced recovery delays in successive conversions. |
Key Features
| Feature | Design Value |
|---|---|
| Separate preamp + PGA architecture | Enables independent optimization: ultra-low-noise amplification first, then programmable gain without degrading SNR. |
| Externally accessible preamp output | Allows insertion of anti-aliasing filters or gain-trimming resistors between stages-no redesign needed for bandwidth or DC offset tuning. |
| Dual-level output clamping | Prevents PGA output from exceeding ADC common-mode range; eliminates need for external clamp diodes or op-amp limiters. |
| Independent per-channel shutdown | Reduces total supply current to ≤1.2 mA per disabled channel-critical for battery-powered multi-sensor nodes. |
| PowerPAD™ thermal package | Exposes die paddle as thermal path to PCB copper; achieves 4.48 W max dissipation at 25°C ambient-supports continuous high-speed operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PGA205U | Single-channel, ±15 V only, fixed ±1/±2/±4/±8 V output ranges; no preamp stage; 100 kHz bandwidth. | Limited to low-frequency, fixed-range applications; lacks THS7002IPWPR's dual-channel independence and high-speed capability. | Select PGA205U only for cost-sensitive, DC-coupled industrial sensors where bandwidth <100 kHz suffices and dual-channel operation is unnecessary. |
| AD8253ARMZ | Single-channel, rail-to-rail output, SPI interface, 35 MHz bandwidth, 10 nV/√Hz input noise, −40°C to +125°C rating. | Requires microcontroller SPI overhead; lower bandwidth and higher noise than THS7002IPWPR preamp; superior temp range. | Choose AD8253ARMZ when system already uses SPI infrastructure and extended temperature operation beyond +85°C is mandatory. |
Compared with PGA205U and AD8253ARMZ, THS7002IPWPR uniquely combines dual-channel independence, integrated low-noise preamp + high-speed PGA, parallel TTL gain control, and PowerPAD thermal performance-making it optimal for space-constrained, high-fidelity, multi-sensor analog front-ends operating up to 85°C.

FAQ
What is the function of the PREAMP OUT pin on the THS7002IPWPR?
The PREAMP OUT pin on the THS7002IPWPR provides direct access to the output of the low-noise preamplifier stage before the programmable-gain amplifier. This allows designers to insert external passive filters (e.g., RC anti-aliasing networks) or fine-tune gain with discrete resistors without affecting the PGA's digital control interface. Its accessibility supports flexible signal conditioning architectures in mixed-signal systems.
Does the THS7002IPWPR support single-supply operation?
No, the THS7002IPWPR requires dual ±4.5 V to ±16 V split supplies and does not support true single-supply operation. Its internal circuitry-including preamp and PGA stages-is optimized for symmetric rails, and the datasheet specifies absolute maximum ratings, operating conditions, and performance parameters exclusively for split-supply configurations. Attempting single-supply biasing violates recommended operating conditions and risks functional failure.
How does the THS7002IPWPR handle output overvoltage conditions?
The THS7002IPWPR employs dedicated CLAMP+ (VH) and CLAMP− (VL) terminals to define hard voltage limits for both PGA outputs. When the output attempts to exceed these thresholds, internal circuitry actively clamps the signal-ensuring it stays within safe bounds for downstream ADCs. Clamp accuracy is ±80 mV over temperature at ±5 V supply, and recovery time after overdrive is under 7 ns, preserving signal integrity during transient events.
What is the thermal design requirement for the THS7002IPWPR's PowerPAD package?
The THS7002IPWPR's PowerPAD™ TSSOP-28 package requires the exposed thermal pad to be soldered to a PCB copper plane tied to GND for effective heat dissipation. Without this connection, junction temperature may exceed 150°C even at moderate loads, risking permanent damage. At TA = 25°C, the device dissipates up to 4.48 W; derating is 35.9 mW/°C above 25°C, necessitating careful thermal layout in high-power-density designs.
Can the THS7002IPWPR's gain be changed dynamically during signal acquisition?
Yes, the THS7002IPWPR supports real-time gain changes via its three TTL-compatible digital inputs (G2/G1/G0). Gain-change delay time is specified at 2 µs-fast enough to adapt gain between successive samples in high-speed data acquisition. However, transient settling (to 0.1%) takes 120–125 ns depending on supply voltage, so timing margins must accommodate this when synchronizing gain updates with sample clocks.
