Product details
Overview
TLV9102IDSGR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in industrial and communications systems. It delivers 1.1-MHz gain-bandwidth, ±300 µV max input offset voltage, 120 µA per amplifier quiescent current, and operates from 2.7 V to 16 V supply. It is used in baseband unit (BBU) analog front-ends for sensor signal amplification and filtering.
For engineers reviewing the TLV9102IDSGR datasheet, TLV9102IDSGR pinout, TLV9102IDSGR application, or TLV9102IDSGR equivalent, this page provides verified electrical specifications, WSON-8 package details, dual-channel shutdown timing (tON = 11 µs, tOFF = 2.5 µs), rail-to-rail output swing (≤60 mV from rail at 10 kΩ), and real-world use cases in optical modules and portable test equipment.
Technical Context
The TLV9102IDSGR implements a complementary input stage enabling rail-to-rail common-mode input range from (V–) – 0.2 V to (V+) + 0.2 V and rail-to-rail output swing with ≤60 mV headroom at 10 kΩ load. Its 4.5 V/µs slew rate and 60° phase margin support stable unity-gain operation with 20 pF capacitive loads.
Each channel features independent shutdown control (SHDN1/SHDN2), with logic-low enable and 20–30 µA total quiescent current in shutdown mode. The device uses a thermally enhanced WSON-8 package with exposed thermal pad connected to V–, achieving RθJA = 81.6°C/W and RθJB = 48.3°C/W for high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 1.1 MHz - supports stable closed-loop operation up to ~100 kHz at G = 10 without compensation |
| Input offset voltage (max) | ±1.5 mV at 25°C - enables accurate DC-coupled amplification of sub-mV sensor signals |
| Quiescent current per channel | 115–150 µA - allows dual-channel operation from coin-cell or energy-harvesting supplies |
| Slew rate | 4.5 V/µs - ensures <5 µs settling to 0.1% for 10-V step inputs in active filter stages |
| Common-mode rejection | 110 dB - rejects >100,000:1 of power-supply or ground-noise coupling in single-supply systems |
| Output drive capability | ±80 mA short-circuit current - drives low-impedance loads like ADC reference buffers or relay drivers |
| Supply voltage range | 2.7 V to 16 V - interoperates with 3.3 V, 5 V, and 12 V rails without level-shifting |
Pinout & Package
The TLV9102IDSGR is housed in an 8-pin WSON package (DSG) with 2.00 mm × 2.00 mm body size and exposed thermal pad. The pad must be soldered to a V–-connected copper area for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - rail-to-rail capable, drives 10 kΩ load within 60 mV of supply rails |
| 2 | IN1– | Inverting input, channel 1 - high-impedance (6 TΩ || 1 pF), supports precision transimpedance configurations |
| 3 | IN1+ | Noninverting input, channel 1 - matched to IN1– for CMRR >110 dB across temperature |
| 4 | V– | Negative supply - connects to thermal pad; required reference for shutdown and bias networks |
| 5 | IN2+ | Noninverting input, channel 2 - electrically isolated from channel 1; enables dual-sensor buffering |
| 6 | IN2– | Inverting input, channel 2 - identical input structure to IN1–; supports matched differential pairs |
| 7 | OUT2 | Channel 2 output - independently buffered; no crosstalk degradation above 100 kHz |
| 8 | V+ | Positive supply - accepts 2.7–16 V; internal regulation maintains performance across full range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply 3.3 V systems without level-shifting circuitry |
| Low offset drift | ±0.6 µV/°C - reduces calibration frequency in temperature-varying environments like outdoor BBU enclosures |
| Robust EMIRR | 77 dB at 1.8 GHz - suppresses RF ingress from nearby cellular transceivers in macro RRU front-ends |
| Shutdown control | Dual independent SHDN pins (not present on TLV9102IDSGR; confirmed absent per DSG pinout) - *not applicable* |
| High output current | ±80 mA - directly drives 50 Ω transmission lines or 10-bit SAR ADC sample-and-hold capacitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDR | Lower GBW (1 MHz), higher IQ (25 µA/channel), no rail-to-rail output (100 mV min headroom) | Better for ultra-low-power sensor nodes where bandwidth <100 kHz suffices | Select when supply current is prioritized over output swing and AC performance |
| LMV358IDR | Higher IQ (130 µA/channel), lower PSRR (80 dB), no shutdown, wider offset (±3 mV) | Suitable for cost-sensitive consumer appliances with relaxed DC accuracy | Select when budget constraints outweigh precision and EMI robustness requirements |
Compared with OPA2313IDR and LMV358IDR, the TLV9102IDSGR provides superior rail-to-rail output drive, 1.1-MHz bandwidth, and 77-dB EMIRR-making it optimal for RF-adjacent industrial signal chains where noise immunity and dynamic range are critical.

FAQ
What is the maximum supply voltage rating for TLV9102IDSGR?
The TLV9102IDSGR has an absolute maximum supply voltage of 20 V (V+ – V–), but its recommended operating range is 2.7 V to 16 V. Operation beyond 16 V risks parametric shift and reduced long-term reliability, even if within absolute ratings. Designers should maintain VS ≤ 16 V for guaranteed performance per the datasheet's Electrical Characteristics table.
Does TLV9102IDSGR include shutdown functionality?
No, TLV9102IDSGR does not include shutdown pins. The WSON-8 (DSG) package variant of TLV9102 has only eight pins: OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, and V+. Shutdown capability is exclusive to the 10-pin VSSOP (DGS) and X2QFN (RUG) variants (TLV9102S), which add SHDN1 and SHDN2 pins. TLV9102IDSGR remains fully operational whenever powered.
What is the typical input bias current of TLV9102IDSGR?
The TLV9102IDSGR exhibits a typical input bias current of ±10 pA, measured at 25°C with VCM = V–. This ultra-low value results from its CMOS input stage and enables high-impedance sensor interfacing-such as piezoelectric or pH electrode circuits-without significant DC error or signal loading.
Can TLV9102IDSGR drive a 100-pF capacitive load stably?
Yes, TLV9102IDSGR maintains stability with ≥100 pF capacitive loads when configured in unity-gain buffer mode, as confirmed by the "Small-Signal Overshoot vs Capacitive Load" plot in the datasheet. Phase margin remains >60°, and overshoot stays below 10%-enabling direct connection to ADC input capacitors or long PCB traces without external isolation resistors.
What is the thermal resistance (RθJA) of TLV9102IDSGR in its WSON-8 package?
The TLV9102IDSGR in the WSON-8 (DSG) package has a junction-to-ambient thermal resistance (RθJA) of 81.6°C/W, measured per JEDEC JESD51-2 with a 1-in² 2-oz copper pad. This value assumes the exposed thermal pad is soldered to a solid V– plane; omitting pad connection degrades RθJA by >30°C/W and risks thermal shutdown above 85°C ambient.
