Product details
Overview
TLV9062IDGKR 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, 10nV/√Hz input voltage noise, 538µA quiescent current per channel, and operates from 1.8V to 5.5V supply. It is used in low-side current sensing and HVAC signal conditioning where precision, low power, and wide supply range are critical.
For engineers reviewing the TLV9062IDGKR datasheet, TLV9062IDGKR pinout, TLV9062IDGKR application, or TLV9062IDGKR equivalent, this page provides verified package mapping (VSSOP-8), confirmed dual-channel op-amp identity, exact pin functions, real-world application context for e-bikes and wearable devices, and two validated alternative parts with documented technical differences.
Technical Context
The TLV9062IDGKR implements a CMOS input stage enabling ultra-low input bias current (0.5pA) and rail-to-rail common-mode input range extending 0.1V beyond both rails. Its resistive open-loop output impedance (100Ω at 10MHz) simplifies stability with capacitive loads up to 100pF and supports robust operation under overdrive without phase reversal.
It features integrated RFI/EMI filtering, unity-gain stability, and extended temperature operation from –40°C to +125°C. The device is not a shutdown variant (TLV9062S), so it lacks SHDN pins and draws continuous quiescent current - distinguishing it from the 10-pin TLV9062S VSSOP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - enables compact dual-signal conditioning in one IC |
| Unity-gain bandwidth | 10MHz - supports fast-settling sensor interfaces and active filter designs up to ~1MHz closed-loop |
| Input offset voltage | ±0.3mV (typ) - ensures <0.5% error in 12-bit ADC front-ends with ±2V input range |
| Supply voltage range | 1.8V to 5.5V - compatible with single-cell Li-ion, 3.3V logic, and legacy 5V systems |
| Quiescent current | 538µA per channel - enables always-on monitoring in battery-powered smoke detectors and wearables |
| Input voltage noise | 10nV/√Hz at 10kHz - preserves SNR in precision instrumentation amplifiers and low-level transducer interfaces |
| CMRR | 103dB (typ) at 5.5V - rejects common-mode interference in noisy motor-control environments |
Pinout & Package
The TLV9062IDGKR is housed in an 8-pin VSSOP (DGK) package measuring 3.0mm × 3.0mm, with exposed thermal pad connected to V– for improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1– (Pin 2) | Inverting input, Channel 1 | Accepts feedback network for inverting configurations; referenced to V– for rail-to-rail operation |
| IN1+ (Pin 3) | Noninverting input, Channel 1 | Direct connection point for high-impedance sensors; supports common-mode range down to V– – 0.1V |
| IN2– (Pin 6) | Inverting input, Channel 2 | Enables dual-path signal processing - e.g., differential pair with IN1–/IN1+ and IN2–/IN2+ |
| IN2+ (Pin 5) | Noninverting input, Channel 2 | Independent high-Z node for second analog channel; no crosstalk with Channel 1 inputs |
| OUT1 (Pin 1) | Output, Channel 1 | Rail-to-rail swing (within 20mV of rails at 10kΩ load) - drives ADC references or low-voltage comparators |
| OUT2 (Pin 7) | Output, Channel 2 | Full output drive capability identical to OUT1 - supports dual-output active filters or redundant sensing paths |
| V– (Pin 4) | Negative supply / ground | Reference for both channels; thermal pad must be soldered to PCB ground plane for thermal reliability |
| V+ (Pin 8) | Positive supply | Single-supply operation supported; supplies both amplifiers - no separate bias rails required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8V–5.5V single-supply systems without level-shifting circuitry |
| Low input bias current (0.5pA) | Prevents signal degradation in high-impedance pH sensors, photodiode transimpedance stages, and piezoelectric interfaces |
| Internal RFI/EMI filter | Reduces susceptibility to GSM bursts, switching regulator noise, and RF ingress without external ferrites or RC networks |
| Resistive open-loop output impedance | Eliminates need for isolation resistors when driving >100pF loads - simplifies layout in motor control gate-drive buffers |
| Extended temperature range (–40°C to +125°C) | Validated for under-hood automotive modules, industrial HVAC controllers, and outdoor e-bike battery management |

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; SOIC-8 package (4.9mm × 3.9mm), higher RθJA (157.6°C/W) vs DGK's 201.2°C/W | Less suitable for space-constrained PCBs; better for manual assembly or legacy footprints | Select TLV9062IDR only if SOIC-8 footprint is fixed and thermal margin ≥20°C exists at 5.5V/125°C |
| OPA2316IDR | Lower bandwidth (10MHz same), but higher offset (±0.75mV), higher IQ (400µA), no EMI filter, wider supply (1.8V–5.5V) | Lacks integrated RFI rejection; requires external filtering in noisy motor-drive environments | Choose OPA2316IDR only when cost sensitivity outweighs EMI robustness needs and offset tolerance >0.75mV is acceptable |
Compared with TLV9062IDGKR, TLV9062IDR offers identical performance in a larger, more thermally resistive package, while OPA2316IDR trades EMI immunity and lower offset for slightly lower quiescent current - making TLV9062IDGKR optimal for compact, noise-prone, precision-sensing applications.

FAQ
What is the supply voltage range for the TLV9062IDGKR?
The TLV9062IDGKR operates from a total supply voltage (V+ to V–) of 1.8V to 5.5V. This allows single-supply use with 1.8V logic, 3.3V microcontrollers, or 5V legacy systems. Operation below 1.8V is not specified and may result in degraded parameters including reduced open-loop gain and increased offset voltage. The device is fully characterized across this range at temperatures from –40°C to +125°C.
Does the TLV9062IDGKR include a shutdown function?
No, the TLV9062IDGKR does not include a shutdown function. It is the standard dual op-amp variant of the TLV906x family. Shutdown capability is exclusive to the TLV9062S series (e.g., TLV9062SDGS), which adds dedicated SHDN1 and SHDN2 pins and reduces quiescent current to <1.5µA per channel in disabled state. TLV9062IDGKR draws 538µA per channel continuously.
What is the thermal resistance (RθJA) of the TLV9062IDGKR in its VSSOP-8 package?
The junction-to-ambient thermal resistance (RθJA) of the TLV9062IDGKR in the DGK (VSSOP-8) package is 201.2°C/W, as specified in the official datasheet Section 6.6. This value assumes standard JEDEC 2-layer board conditions. Actual thermal performance improves significantly when the exposed thermal pad is soldered to a solid copper ground plane - reducing effective RθJA by up to 40% in optimized layouts.
Can the TLV9062IDGKR drive capacitive loads greater than 100pF?
Yes - the TLV9062IDGKR's resistive open-loop output impedance (100Ω at 10MHz) enables stable operation with capacitive loads exceeding 100pF, unlike many CMOS op-amps that require isolation resistors. Small-signal overshoot remains under 10% up to 300pF (per Figure 6-23). For loads >100pF, maintain layout best practices: minimize trace length, avoid stubs, and place load close to the output pin.
Is the TLV9062IDGKR pin-compatible with other TLV9062 variants?
No - TLV9062IDGKR (VSSOP-8, no shutdown) is not pin-compatible with TLV9062S variants (e.g., TLV9062SDGS in VSSOP-10 or TLV9062SRUG in X2QFN-10), which add two shutdown pins. It shares the same 8-pin functional pinout as TLV9062IDR (SOIC-8) and TLV9062IDD (TSSOP-8), but mechanical compatibility requires verifying land pattern dimensions and thermal pad requirements - especially for the DGK package's exposed pad.
