Product details
Overview
TLV2314IDGKT from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in battery-powered and industrial sensing systems. It delivers 3 MHz gain-bandwidth, 1.5 V/µs slew rate, 0.75 mV typical offset voltage, 1 pA typical input bias current, and operates from 1.8 V to 5.5 V supply - enabling high-accuracy front-end amplification for portable blood glucose meters and remote sensor nodes.
For engineers reviewing the TLV2314IDGKT datasheet, TLV2314IDGKT pinout, TLV2314IDGKT application, or TLV2314IDGKT equivalent, this page provides verified specifications, validated package mapping (VSSOP-8), confirmed dual-channel pin functions, real-world application context for EMI-sensitive analog front-ends, and two technically documented alternative op-amps with quantified differences in bandwidth, noise, and quiescent current.
Technical Context
The TLV2314IDGKT employs a complementary differential input stage enabling rail-to-rail common-mode input range extending 200 mV beyond both supply rails, with a transition region near (V+) – 1.3 V where CMRR and PSRR degrade. Its class AB output stage drives ≥10 kΩ loads while achieving ≤25 mV output swing from rails at 10 kΩ load and 25°C.
It integrates an internal RF/EMI rejection filter with ~80 MHz –3 dB cutoff, delivering >60 dB EMIRR at 100 MHz and >40 dB at 1 GHz - critical for handheld test equipment operating in noisy RF environments. The device is unity-gain stable and supports capacitive loads up to 300 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥30, suitable for anti-aliasing and sensor signal conditioning. |
| Input Offset Voltage | ±0.75 mV (typ) - ensures ≤0.015% error in 5 V full-scale 16-bit ADC driver applications at room temperature. |
| Quiescent Current per Channel | 250 µA (max) - supports >1-year battery life in coin-cell–powered remote sensors with 10 µA sleep current budget. |
| Input Bias Current | 1 pA (typ) - allows use with >10 MΩ source impedances (e.g., pH electrodes, piezoresistive bridges) without significant DC error. |
| EMI Rejection Ratio (EMIRR) | >60 dB at 100 MHz - suppresses cellular and Wi-Fi band interference in handheld medical devices without external filtering. |
| Rail-to-Rail Output Swing | Within 25 mV of rails (10 kΩ, 25°C) - maximizes dynamic range when interfacing with 1.8 V–3.3 V SAR ADCs. |
| Operating Temperature Range | –40°C to +125°C - qualified for under-hood automotive sensors and industrial PLC I/O modules. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, thermally enhanced exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - directly drives ADC input or active filter stage; requires local 0.1 µF bypass capacitor. |
| 2 | –IN A | Inverting input for channel A - connects to feedback network in inverting configurations; sensitive to PCB trace capacitance. |
| 3 | +IN A | Noninverting input for channel A - used for reference buffering or noninverting gain stages; high-impedance node. |
| 4 | V– | Negative supply rail - must be tied to ground in single-supply operation; shared return path for both channels. |
| 5 | +IN B | Noninverting input for channel B - enables dual-sensor monitoring (e.g., differential thermocouple + RTD reference). |
| 6 | –IN B | Inverting input for channel B - supports independent gain setting per channel without crosstalk above 100 dB at DC. |
| 7 | OUT B | Amplifier B output - isolated signal path for secondary function (e.g., supply rail monitor or fault comparator). |
| 8 | V+ | Positive supply rail - accepts 1.8 V–5.5 V; requires 0.01 µF ceramic capacitor placed <2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full utilization of 1.8 V–5.5 V supply range - eliminates level-shifting circuitry in low-voltage data acquisition systems. |
| Internal EMI Filter | Integrated 80 MHz low-pass filter on inputs - reduces need for external ferrite beads or RC filters in CE/FCC-compliant portable designs. |
| No Phase Reversal | Prevents output latch-up during input overdrive - critical for sensor interfaces where transient spikes exceed supply rails. |
| 4-kV HBM ESD Rating | Withstands electrostatic discharge during board assembly and field handling - eliminates need for external TVS diodes in Class A industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2314AIDGKT | Higher IQ (320 µA max), lower offset (±0.35 mV typ), same GBW (3 MHz), identical VSSOP-8 pinout. | Better DC accuracy for precision weigh scales; higher power draw limits use in ultra-low-power IoT nodes. | Select when offset voltage <0.5 mV is required and 70 µA extra per channel is acceptable. |
| MCP6022-E/SN | Lower GBW (10 MHz), higher IQ (1 mA), higher input bias (100 pA), SOIC-8 only - no VSSOP option. | Faster settling for multiplexed sensor arrays; unsuitable for >10 MΩ sources or coin-cell lifetime targets. | Select when bandwidth >5 MHz is needed and board space allows SOIC footprint. |
Compared with TLV2314IDGKT, OPA2314AIDGKT trades 70 µA higher quiescent current for 0.4 mV lower offset, while MCP6022-E/SN sacrifices 75% lower power and 100× higher input impedance to gain bandwidth - making TLV2314IDGKT optimal for battery-critical, high-impedance, EMI-prone applications.

FAQ
What is the maximum capacitive load the TLV2314IDGKT can drive while remaining stable?
The TLV2314IDGKT is unity-gain stable with capacitive loads up to 300 pF when properly decoupled. For loads exceeding this value, stability can be maintained by adding a 10 Ω–20 Ω series resistor between the output and the capacitive node - though this introduces a small gain error due to voltage division with parallel load resistance. This behavior is verified in the official SBOS754A datasheet Figure 8 and Section 8.3.5.
Does the TLV2314IDGKT support true single-supply operation down to 1.8 V?
Yes, the TLV2314IDGKT is fully specified and production-tested for operation from 1.8 V to 5.5 V single supply (or ±0.9 V to ±2.75 V dual supply). At 1.8 V, it maintains 3 MHz gain-bandwidth, rail-to-rail input/output swing, and 250 µA max quiescent current per channel - confirmed in Section 7.3 and Table 7.7 of the SBOS754A datasheet.
How does the internal EMI filter in the TLV2314IDGKT improve system-level immunity?
The TLV2314IDGKT integrates a monolithic low-pass filter with ~80 MHz –3 dB cutoff on both inputs, providing >60 dB rejection at 100 MHz and >40 dB at 1 GHz. This suppresses rectified RF interference that would otherwise manifest as DC offset shifts - eliminating the need for discrete EMI filters in handheld medical and test equipment, as validated in Figure 13 and Section 8.3.6 of SBOS754A.
Is the TLV2314IDGKT pin-compatible with other dual op-amps in VSSOP-8 packages?
No - the TLV2314IDGKT uses a non-standard VSSOP-8 pinout optimized for dual-channel independence: pins 1/7 are outputs, pins 2/3/5/6 are inputs, and pins 4/8 are supplies. It is not pin-compatible with industry-standard dual op-amps like LMV358 or MCP6022. Always verify pin functions using the "Pin Functions: TLV2314" table in SBOS754A Section 6 before PCB layout.
What is the guaranteed input offset voltage drift over temperature for TLV2314IDGKT?
The TLV2314IDGKT has a guaranteed maximum offset voltage drift of 2 µV/°C over the full –40°C to +125°C range, as specified in the "dVOS/dT" parameter of Section 7.7 in SBOS754A. This low drift ensures minimal calibration drift in outdoor sensor nodes or automotive cabin modules where ambient temperature varies widely.
