Product details
Overview
TLV313IDCKT from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for ultra-low-power, cost-sensitive systems. It delivers 1-MHz gain-bandwidth, 65 µA typical quiescent current per channel, 26 nV/√Hz input voltage noise at 1 kHz, 0.75 mV typical offset voltage, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy signal conditioning in battery-powered medical sensors and utility metering front-ends.
For engineers reviewing the TLV313IDCKT datasheet, TLV313IDCKT pinout, TLV313IDCKT application, or TLV313IDCKT equivalent, this page provides verified specifications, SC70-5 package details, real-world use cases in wearable biosensing and heat-meter analog front-ends, and validated alternative op-amps with documented parameter trade-offs.
Technical Context
The TLV313IDCKT employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail input operation with ±0.2 V beyond supply rails and no phase reversal under overdrive. Its class AB output stage achieves rail-to-rail output swing - typically within 5 mV of either rail at 100-kΩ load - while maintaining unity-gain stability up to 150 pF capacitive load.
It integrates an internal RF/EMI filter on input pins to suppress rectification-induced offset shifts from high-frequency interference, and features 4-kV HBM ESD protection. The device is fully characterized from –40°C to +125°C and specified for low-noise, low-drift performance across its 1.8–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - supports direct connection to Li-ion, coin-cell, or 3.3 V/5 V system rails without regulation. |
| Quiescent Current | 65 µA/ch - enables multi-year battery life in always-on wearable and metering applications. |
| Gain Bandwidth | 1 MHz - sufficient for driving 12-bit SAR ADCs with <1 LSB error at 100 kSPS sampling rates. |
| Input Offset Voltage | 0.75 mV (typ) - ensures ≤0.5% gain error in 100-mV full-scale sensor interfaces without trimming. |
| Input Voltage Noise | 26 nV/√Hz at 1 kHz - preserves SNR in low-level thermistor or strain-gauge amplification stages. |
| CMRR / PSRR | 85 dB / 90 dB - rejects common-mode noise from shared PCB ground and supply ripple in mixed-signal systems. |
| Operating Temperature | –40°C to +125°C - qualified for industrial metering enclosures and automotive cabin ambient zones. |
Pinout & Package
TLV313IDCKT is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm body), optimized for space-constrained portable designs. Pin functions are electrically identical to SOT23-5 but with smaller footprint and thermal resistance of 281.4°C/W (RθJA).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN | Noninverting input - accepts signals from 0.2 V below V– to 0.2 V above V+ with no phase reversal. |
| 2 | V– | Negative supply terminal - referenced to system ground in single-supply configurations. |
| 3 | –IN | Inverting input - used in transimpedance or difference-amplifier topologies with 1 pA bias current. |
| 4 | OUT | Amplifier output - drives loads up to 100 kΩ with rail-to-rail swing (≤5 mV from rails) and 0.5 V/µs slew rate. |
| 5 | V+ | Positive supply terminal - supplies power and sets common-mode range; tolerant of 7 V absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends ±0.2 V beyond supply rails; output swings to within 5 mV of V+ or V– at light loads - eliminates level-shifting in 1.8–5.5 V systems. |
| Low IQ | 65 µA/ch - reduces total system standby power in multi-op-amp sensor nodes (e.g., 4-channel gas sensor arrays). |
| EMI Filtering | Integrated RF/EMI rejection filter on inputs - prevents offset shift from GSM/ISM-band interference in portable healthcare devices. |
| Unity-Gain Stable | Stable with ≥150 pF capacitive load - simplifies layout for ADC driver or filter buffer without external compensation. |
| High CMRR | 85 dB over linear input range - maintains accuracy when amplifying low-level bridge outputs in noisy industrial environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA313IDBVR | Higher IQ (75 µA), lower offset (0.35 mV typ), same SC70-5 package and 1-MHz GBW. | Better DC accuracy for precision weigh scales; higher power disfavors multi-year battery use. | Select OPA313IDBVR when offset voltage dominates error budget and supply headroom permits extra 10 µA. |
| MCP6001UT-E/OT | Lower IQ (1 µA), lower GBW (100 kHz), wider offset range (1.5 mV max), SOT23-5 only. | Suitable for slow, ultra-low-power sensor wake-up circuits; insufficient bandwidth for fast ADC drivers. | Choose MCP6001UT-E/OT only for sub-10-kSPS sampling or where <1 µA standby current is mandatory. |
Compared with TLV313IDCKT, OPA313IDBVR trades 10 µA higher quiescent current for 0.4 mV lower offset, while MCP6001UT-E/OT sacrifices 900 kHz bandwidth and 0.75 mV offset accuracy to achieve nanoamp-level standby - making TLV313IDCKT the optimal balance for 100-kSPS+ portable instrumentation.

FAQ
What is the maximum capacitive load the TLV313IDCKT can drive while remaining stable?
The TLV313IDCKT remains unity-gain stable with capacitive loads up to 150 pF. For larger loads (e.g., ADC input capacitance >10 pF plus PCB trace capacitance), adding a 10–20 Ω series resistor between the TLV313IDCKT output and the load restores stability without compromising DC accuracy significantly. This technique is validated in TI's SBOS753B datasheet Figure 19.
Does TLV313IDCKT support true rail-to-rail input at 1.8 V supply?
Yes. TLV313IDCKT guarantees rail-to-rail input operation from (V–) – 0.2 V to (V+) + 0.2 V across its full 1.8–5.5 V supply range, including at 1.8 V. At minimum supply, the common-mode range spans –0.2 V to +2.0 V, enabling direct interface with low-voltage sensors and reference buffers without level shifting.
What is the typical input bias current of TLV313IDCKT and why does it matter?
The TLV313IDCKT has a typical input bias current of ±1 pA. This ultra-low value minimizes voltage error across high-impedance sources (e.g., >1 MΩ thermistors or photodiodes), preserving signal integrity in precision sensor interfaces where even nanoamp-level leakage would cause measurable offset.
Can TLV313IDCKT operate from a single 1.8 V supply in a battery-powered wearable?
Yes. TLV313IDCKT is fully specified and tested at 1.8 V, drawing only 65 µA typical quiescent current. Its rail-to-rail input/output capability allows full utilization of the 0–1.8 V range, making it ideal for direct integration with coin-cell or LiFePO₄ batteries in wearables without voltage boosting or regulation.
How does the internal EMI filter in TLV313IDCKT improve system reliability?
The integrated RF/EMI filter on TLV313IDCKT's input pins suppresses rectification-induced DC offset shifts caused by GSM, Wi-Fi, or Bluetooth interference. In wearable and medical devices, this prevents false alarms or measurement drift during wireless transmission - a key reliability feature confirmed in TI's EMI immunity characterization (Figure 18, SBOS753B).
