Product details
Overview
TLV314IDCKR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-power, high-EMI-immunity signal conditioning in battery-powered systems. It delivers 3 MHz gain bandwidth, 1.5 V/µs slew rate, and 250 µA max quiescent current per channel while operating from 1.8 V to 5.5 V supply - enabling precision sensor interfacing in portable blood glucose meters and handheld test equipment.
For engineers reviewing the TLV314IDCKR datasheet, TLV314IDCKR pinout, TLV314IDCKR application, or TLV314IDCKR equivalent, key selection criteria include its 1 pA typical input bias current for high-impedance MΩ source networks, internal 80-MHz RF/EMI filter verified to 6 GHz, and guaranteed rail-to-rail operation across –40°C to +125°C for industrial automation and white goods control loops.
Technical Context
The TLV314IDCKR employs a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail input common-mode range extending 200 mV beyond both supply rails. Its class AB output stage drives ≤10 kΩ loads with output swing to within 5 mV of either rail at 25°C under 10 kΩ load.
Stability is unity-gain guaranteed with capacitive load drive up to 1 nF; internal EMI filtering provides >60 dB EMIRR IN+ rejection at 100 MHz and maintains performance through 1 GHz. No phase reversal occurs during overdrive, and 4-kV HBM ESD protection ensures robustness in production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - supports stable closed-loop amplification up to ~200 kHz at G = 10 without peaking |
| Input Offset Voltage | ±0.75 mV (typ) - enables <1 LSB error in 12-bit ADC front-ends with ±2.5 V reference |
| Quiescent Current | 250 µA/Ch (max) - allows continuous operation for >1 year on a single CR2032 coin cell in sleep-wake sensor nodes |
| Input Bias Current | 1 pA (typ) - preserves signal integrity in pH electrode, photodiode, or thermistor circuits with >100 MΩ source impedance |
| EMI Rejection Ratio | >60 dB at 100 MHz - suppresses RF rectification-induced DC offset shift in noisy industrial or medical EMI environments |
| Rail-to-Rail Output Swing | Within 5 mV of V+ or V– at 10 kΩ - maximizes dynamic range for 1.8 V–5.5 V supply ADC drivers |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive sensors and factory-floor PLC I/O modules |
Pinout & Package
TLV314IDCKR is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm body), optimized for space-constrained PCB layouts in portable instrumentation and wearable health monitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Class AB buffered voltage output capable of sourcing/sinking ±20 mA; swings rail-to-rail into 10 kΩ |
| 2 (V–) | Negative Supply | Reference node for single-supply (ground) or dual-supply (–V) operation; must be bypassed with 0.01 µF ceramic |
| 3 (+IN) | Noninverting Input | High-impedance node (1 pA bias) accepting signals from 200 mV below V– to 200 mV above V+; EMI-filtered |
| 4 (–IN) | Inverting Input | Differential input paired with +IN; matched input capacitance (1 pF diff / 5 pF cm) minimizes phase error in transimpedance amps |
| 5 (V+) | Positive Supply | Primary power rail (1.8–5.5 V); supplies internal bias and output stage; requires local 0.01 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF/EMI Filter | 80-MHz low-pass filter (–3 dB) with 20 dB/decade roll-off suppresses rectified offset drift from 10 MHz–6 GHz interference |
| No Phase Reversal | Guaranteed behavior during input overdrive prevents latch-up or uncontrolled output saturation in sensor fault conditions |
| Capacitive Load Stability | Unity-gain stable with ≤1 nF pure capacitive load; supports direct connection to ADC sample-and-hold inputs without external isolation |
| Extended Temp Range | Full electrical specification maintained from –40°C to +125°C - eliminates derating calculations for industrial motor control feedback paths |
| ESD Protection | 4-kV HBM rating enables handling without special ESD workstations during manual assembly of medical device PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA314AIDBVR | Higher 3.6 MHz GBW, 2.5 V/µs slew rate, but 300 µA IQ (vs. 250 µA max for TLV314IDCKR); same SC70-5 package | Better for higher-frequency active filters or faster-settling data acquisition; less optimal for ultra-low-power wake-on-event sensing | Select OPA314AIDBVR when AC performance outweighs quiescent current budget; verify layout compatibility with identical pinout |
| MCP6001UT-E/OT | 1 MHz GBW, 0.6 V/µs slew rate, 100 µA IQ; SC70-5 package; no integrated EMI filter or extended temperature grade | Suitable for cost-sensitive consumer electronics where EMI immunity and industrial temp range are not required | Choose MCP6001UT-E/OT only for non-critical commercial applications; avoid in medical or industrial settings requiring EMI resilience or >85°C operation |
Compared with OPA314AIDBVR and MCP6001UT-E/OT, TLV314IDCKR uniquely balances 3 MHz bandwidth, sub-250 µA quiescent current, integrated EMI filtering, and full –40°C to +125°C qualification - making it the only option meeting all four requirements simultaneously for portable medical and ruggedized industrial designs.

FAQ
What is the maximum capacitive load TLV314IDCKR can drive stably in unity-gain configuration?
The TLV314IDCKR remains unity-gain stable with a pure capacitive load up to approximately 1 nF, as confirmed by characterization data in the SBOS754A datasheet Figure 8. For larger loads, adding a 10–20 Ω series resistor at the output improves stability but introduces gain error due to voltage division with parallel resistive loads. TLV314IDCKR's internal compensation eliminates need for external compensation networks in standard configurations.
Does TLV314IDCKR support true rail-to-rail input operation across its full supply range?
Yes, TLV314IDCKR achieves rail-to-rail input operation with common-mode voltage range extending 200 mV beyond both V+ and V– rails - from (V–) – 0.2 V to (V+) + 0.2 V - across its entire 1.8 V to 5.5 V supply range and –40°C to +125°C temperature span. This is enabled by its complementary N/P-channel input stage, as detailed in Section 8.3.2 of the SBOS754A datasheet.
What is the EMI rejection performance of TLV314IDCKR, and how is it implemented?
TLV314IDCKR features an internal low-pass EMI filter with ~80 MHz cutoff (–3 dB) and 20 dB/decade roll-off, providing >60 dB EMIRR IN+ rejection at 100 MHz and validated performance up to 6 GHz. This integrated filter attenuates both common-mode and differential-mode RF interference before it reaches the core amplifier, preventing rectification-induced DC offset shifts - a key differentiator versus standard op-amps like MCP6001.
Can TLV314IDCKR operate from a single 1.8 V supply, and what is its output swing capability at that voltage?
Yes, TLV314IDCKR is fully specified for 1.8 V single-supply operation. At 1.8 V, it delivers rail-to-rail output swing to within 25 mV of each rail under 10 kΩ load (per Electrical Characteristics Table, VO parameter), and to within 45 mV under 2 kΩ load. This enables effective use with low-voltage ADCs and microcontrollers in energy-harvesting and coin-cell-powered devices.
Is TLV314IDCKR pin-compatible with other members of the TLVx314 family, such as TLV2314 or TLV4314?
No, TLV314IDCKR (single-channel, SC70-5) is not pin-compatible with TLV2314 (dual, SOIC/VSSOP-8) or TLV4314 (quad, TSSOP-14). Each variant has distinct pin counts, functions, and footprints. However, all share identical electrical specifications and functional behavior per channel, allowing schematic reuse with appropriate package adaptation and layout revision.
