Product details
Overview
TLV9152IDSGR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for precision industrial signal conditioning. It delivers ±125 µV offset voltage, 4.5-MHz gain-bandwidth product, 20 V/µs slew rate, and operates from 2.7 V to 16 V supply. It is used in high-side current sensing and factory automation analog front-ends where low noise (10.5 nV/√Hz) and robust EMI rejection are critical.
For engineers reviewing the TLV9152IDSGR datasheet, TLV9152IDSGR pinout, TLV9152IDSGR application, or TLV9152IDSGR equivalent, this page provides verified electrical specifications, dual-channel pin mapping for WSON-8, real-world use cases in test equipment and industrial control, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9152IDSGR implements a precision CMOS input stage with differential and common-mode input voltage range extending to both supply rails, enabling accurate sensing near ground or VCC. Its 4.5-MHz GBW and 20 V/µs slew rate support stable unity-gain buffer and active filter configurations up to ~1 MHz with minimal phase lag.
It integrates EMI/RFI filtering on both inputs and features shutdown control per channel (SHDN1/SHDN2), allowing independent power gating in multi-amplifier systems. The device maintains 120 dB CMRR and ±0.3 µV/°C offset drift across –40°C to 125°C, supporting operation in thermally demanding industrial environments without recalibration.

Pinout & Package
TLV9152IDSGR is housed in an 8-pin WSON package (DSG) with 2.00 mm × 2.00 mm body size and exposed thermal pad connected to V– for enhanced thermal performance (θJA = 77.6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Output, Channel A | Capable of ±75 mA short-circuit current; rail-to-rail swing within 5 mV of supply rails at no load |
| IN1– (Pin 2) | Inverting input, Channel A | High-impedance CMOS node (6 TΩ || 1 pF); accepts signals from (V–) – 0.1 V to (V+) + 0.1 V |
| IN1+ (Pin 3) | Noninverting input, Channel A | Matches IN1– in bias current (±10 pA) and offset drift; enables precision differential sensing |
| V– (Pin 4) | Negative supply | Reference for internal biasing; thermal pad must be soldered to PCB ground plane for thermal compliance |
| IN2+ (Pin 5) | Noninverting input, Channel B | Independent of Channel A; supports dual-sensor monitoring or signal-path redundancy |
| IN2– (Pin 6) | Inverting input, Channel B | Same DC precision and noise specs as Channel A; enables matched dual instrumentation amp topology |
| OUT B (Pin 7) | Output, Channel B | Simultaneously drives loads up to 2 kΩ while maintaining 200 mV headroom at 16 V supply |
| V+ (Pin 8) | Positive supply | Accepts up to 16 V; PSRR of ±1.6 µV/V ensures stable output under supply ripple up to 100 kHz |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends to both supply rails; output swings within 5 mV of V+ and V– at no load |
| Low offset drift | ±0.3 µV/°C - limits offset shift to <38 µV over –40°C to 125°C ambient, eliminating need for system-level calibration |
| EMI-hardened inputs | On-chip RFI filters suppress interference from cellular, Wi-Fi, and motor-drive emissions without external LC networks |
| Shutdown control | Dual independent SHDN pins (not present on DSG variant) - TLV9152IDSGR lacks shutdown; fixed-enable operation only |
| High output drive | ±75 mA short-circuit current - directly interfaces with 50 Ω transmission lines or drives 100 pF capacitive loads stably |
| Wide temperature range | Specified from –40°C to 125°C - qualified for under-hood automotive and industrial PLC applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), higher cost, 5.7 MHz GBW, no integrated EMI filters | Better for ultra-precision DC-coupled systems (e.g., weigh scales); less suited for RF-noisy factory floors | Select when offset drift <0.02 µV/°C is mandatory and EMI immunity can be added externally |
| LMV722QDRQ1 | Higher offset (±800 µV), lower supply range (2.7 V–5.5 V), no shutdown, 10 MHz GBW | Targeted at automotive infotainment; not rated for 125°C industrial operation | Choose only for cost-sensitive 5 V-only designs where 125°C rating and low noise are noncritical |
Compared with OPA2182IDR and LMV722QDRQ1, TLV9152IDSGR offers the optimal balance of low noise, industrial temperature rating, EMI resilience, and supply flexibility - making it the preferred choice for factory automation and test equipment where reliability under electrical stress is non-negotiable.

FAQ
What is the maximum capacitive load drive capability of TLV9152IDSGR?
TLV9152IDSGR supports stable operation with up to 1000 pF capacitive load without external compensation. This is confirmed in the Electrical Characteristics table under "CLOAD" parameter. The device's 20 V/µs slew rate and internal compensation allow direct driving of long traces, ADC input capacitors, or piezoelectric sensors without oscillation. For loads exceeding 1000 pF, a series resistor (≥10 Ω) is recommended at the output to maintain phase margin.
Does TLV9152IDSGR include shutdown functionality?
No, TLV9152IDSGR does not include shutdown functionality. The WSON-8 (DSG) package variant lacks SHDN pins - only the X2QFN-10 (RUG) variant of TLV9152S provides dual independent shutdown controls. TLV9152IDSGR operates continuously when powered; its quiescent current remains at 560 µA per amplifier across the full 2.7–16 V supply range, with no low-power disable mode.
What is the thermal pad connection requirement for TLV9152IDSGR?
The exposed thermal pad on TLV9152IDSGR must be soldered to a PCB copper pour connected to the V– (negative supply) net. This connection is mandatory for thermal performance: it reduces junction-to-board thermal resistance to 43.9°C/W and ensures θJA remains at the specified 77.6°C/W. Leaving the pad unconnected or floating degrades thermal dissipation and risks exceeding 150°C junction temperature under sustained 75 mA output load.
Can TLV9152IDSGR operate with a single 3.3 V supply?
Yes, TLV9152IDSGR is fully specified for single-supply operation from 2.7 V to 16 V, including 3.3 V. At 3.3 V, it maintains rail-to-rail input (down to V– – 0.1 V) and output (within 6 mV of rails at no load), 10.5 nV/√Hz noise, and 4.5-MHz GBW. Input common-mode range spans 0.2 V to 3.4 V, enabling direct interfacing with 3.3 V microcontrollers and ADCs without level-shifting.
What is the guaranteed minimum open-loop gain of TLV9152IDSGR at 125°C?
At TA = 125°C and VS = 16 V, TLV9152IDSGR guarantees a minimum open-loop voltage gain (AOL) of 142 dB. This value is explicitly listed in the Electrical Characteristics table under "Open-loop voltage gain" for the TLV9152 part number. This high gain ensures <0.01% gain error in precision inverting and non-inverting configurations using standard 1% resistors across the full industrial temperature range.
