Product details
Overview
TLV9062IDSGT from Texas Instruments is a dual, rail-to-rail input/output CMOS operational amplifier optimized for cost-sensitive, low-voltage systems. It delivers 10MHz unity-gain bandwidth, ±0.3mV input offset voltage, and 538µA quiescent current per channel at 5.5V, operating from 1.8V to 5.5V supply. It is used in low-side current sensing, HVAC sensor conditioning, and wearable device front-ends.
For engineers reviewing the TLV9062IDSGT datasheet, TLV9062IDSGT pinout, TLV9062IDSGT application, or TLV9062IDSGT equivalent, key selection criteria include capacitive load drive stability (resistive open-loop output impedance), shutdown functionality (1µA typical), RFI/EMI filtering, extended temperature range (–40°C to 125°C), and WSON-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV9062IDSGT employs a CMOS input stage enabling ultra-low input bias current (0.5pA) and rail-to-rail common-mode input range (V– – 0.1V to V+ + 0.1V). Its resistive open-loop output impedance simplifies stabilization with capacitive loads beyond 100pF, unlike conventional op-amps requiring external compensation.
It integrates an internal RFI/EMI filter and avoids phase reversal during overdrive. The dual-channel architecture shares a single 8-pin WSON package with exposed thermal pad connected to V–, supporting high-density mixed-signal designs where power efficiency and signal integrity are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - enables direct interface with Li-ion, 3.3V, and 5V logic without level-shifting. |
| Unity-Gain Bandwidth | 10MHz - supports fast-settling active filters and medium-speed sensor signal amplification. |
| Input Offset Voltage | ±0.3mV (typ) - ensures <100µV error in 12-bit ADC front-ends with gain ≤10. |
| Quiescent Current | 538µA per channel - allows dual-opamp operation in battery-powered wearables with >1-year runtime. |
| Input Bias Current | 0.5pA - preserves accuracy in high-impedance pH or photodiode transimpedance circuits. |
| Output Swing | Rail-to-rail - maximizes dynamic range into ADCs or low-voltage comparators without headroom loss. |
| Shutdown Current | 0.5µA (typ) - reduces system standby power when unused channels are disabled. |
Pinout & Package
TLV9062IDSGT uses an 8-pin WSON (DSG) package with 2.00mm × 2.00mm body size and exposed thermal pad. The pad must be soldered to V– for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - drives downstream ADC input or feedback network; rail-to-rail swing. |
| 2 | IN1– | Inverting input, channel 1 - accepts differential or inverting configuration signals; high-impedance CMOS node. |
| 3 | IN1+ | Noninverting input, channel 1 - used for unity-gain buffers or precision reference buffering. |
| 4 | V– | Negative supply or ground - connects to PCB ground plane and thermal pad; defines lower rail. |
| 5 | IN2– | Inverting input, channel 2 - isolated from channel 1; enables independent dual-sensor conditioning. |
| 6 | IN2+ | Noninverting input, channel 2 - supports separate gain-setting resistors per channel. |
| 7 | OUT2 | Channel 2 output - electrically isolated from OUT1; no crosstalk up to 100dB DC channel separation. |
| 8 | V+ | Positive supply - powers both amplifiers; decoupling capacitor required within 1cm. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062IDR | Same electrical specs, but in SOIC-8 (4.9mm × 3.9mm) - 6× larger footprint, higher RθJA (157.6°C/W vs 94.4°C/W). | Suitable for prototyping or legacy through-hole-compatible boards; not for space-constrained wearables. | Select TLV9062IDR only if board real estate permits larger package and thermal performance is less critical. |
| OPA2316IDR | Lower bandwidth (10MHz same), but higher offset (±500µV), higher IQ (400µA), no shutdown, no integrated RFI filter. | Lacks shutdown and EMI filtering - requires external components for battery-powered or noisy environments. | Choose OPA2316IDR only if cost is primary constraint and EMI immunity/shutdown are not required. |
Compared with TLV9062IDSGT, TLV9062IDR trades miniaturization and thermal efficiency for ease of hand-soldering, while OPA2316IDR sacrifices EMI robustness and ultra-low power for marginally lower unit cost - neither offers pin-to-pin compatibility or identical feature set.

FAQ
What is the maximum capacitive load the TLV9062IDSGT can drive without external compensation?
The TLV9062IDSGT is specified for stable operation with ≥100pF capacitive load due to its resistive open-loop output impedance. Test data shows minimal overshoot (<10%) up to 300pF in unity-gain configuration, eliminating need for series isolation resistors in most ADC driver or cable-driving applications. This behavior is confirmed in Figure 6-23 of the SBOS839N datasheet.
Does the TLV9062IDSGT support single-supply operation?
Yes, the TLV9062IDSGT fully supports single-supply operation from 1.8V to 5.5V. Its rail-to-rail input range extends from (V–) – 0.1V to (V+) + 0.1V, and rail-to-rail output swing reaches within 20mV of each rail at 5.5V with 10kΩ load. This enables direct interfacing with microcontrollers and ADCs powered from the same low-voltage rail.
How does the shutdown function work on the TLV9062IDSGT?
The TLV9062IDSGT does not include a shutdown pin - it is the non-shutdown variant of the TLV9062 family. Shutdown functionality is exclusive to TLV9062S part numbers (e.g., TLV9062SIRUGR). The TLV9062IDSGT operates continuously when powered; power cycling or external FET gating is required for standby current reduction.
What is the thermal resistance (RθJA) of the TLV9062IDSGT WSON package?
The TLV9062IDSGT in WSON-8 (DSG) package has a junction-to-ambient thermal resistance (RθJA) of 94.4°C/W, as measured per JEDEC JESD51 standards with 2-layer board layout. This value assumes standard copper pour under the exposed thermal pad connected to V–, enabling reliable operation at 125°C ambient when dissipating ≤125mW per channel.
Is the TLV9062IDSGT qualified for automotive applications?
The TLV9062IDSGT is not AEC-Q200 qualified. While it operates across –40°C to 125°C and meets industrial reliability standards, Texas Instruments does not list it in their automotive-grade product portfolio. For automotive use, consider the pin-compatible TLV9062QDRQ1 (AEC-Q200 Grade 1) or OPA2991QDGKRQ1, which undergo additional stress testing and PPAP documentation.
