Product details
Overview
TLV27L2IDGK from Texas Instruments is a dual micropower rail-to-rail output operational amplifier optimized for low-voltage, high-impedance sensor signal conditioning in industrial and portable systems. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA per-channel quiescent current, 5 mV max input offset voltage, and operates from 2.7 V to 16 V across −40°C to +125°C - enabling use in battery-powered smoke detectors and power monitoring circuits.
For engineers reviewing the TLV27L2IDGK datasheet, TLV27L2IDGK pinout, TLV27L2IDGK application, or TLV27L2IDGK equivalent, this page provides verified package mapping (VSSOP-8 DGK), confirmed rail-to-rail output swing (≤120 mV from rail at VS = 5 V), temperature-rated performance data, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV27L2IDGK employs BiMOS input stage architecture to achieve 1 pA typical input bias current and rail-to-rail output swing using complementary MOSFET output transistors. Its 160 kHz unity-gain bandwidth is sustained across supply voltages from 2.7 V to 16 V and full industrial temperature range.
It features input common-mode voltage range extending from −0.2 V to VS+1.2 V, CMRR of 70–86 dB, PSRR of 70–82 dB, and 89 nV/√Hz input voltage noise - making it suitable for precision DC-coupled amplification where supply headroom and input impedance are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell LiFePO₄ (2.8 V) up to ±8 V dual supplies; enables direct replacement of TLC27L2 in legacy designs. |
| Quiescent Current (per channel) | 7 μA typical / 16 μA max - allows continuous operation for >10 years on a CR2032 coin cell in low-duty-cycle sensor nodes. |
| Gain-Bandwidth Product | 160 kHz - sufficient for anti-aliasing filtering and slow control loops (e.g., thermistor linearization below 100 Hz). |
| Input Offset Voltage | 5 mV max (full range) - ensures ≤0.5% error in 1 V full-scale medical sensor front-ends without trimming. |
| Output Swing (from rail) | 120 mV max at VS = 5 V - delivers >95% of supply range to ADC inputs, maximizing dynamic range utilization. |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying high-impedance sources (e.g., pH electrodes, piezoresistive sensors). |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive power monitoring and industrial motor control feedback paths. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Rail-to-rail output capable of sourcing/sinking ≥100 μA within 120 mV of supply rails at VS = 5 V. |
| 1IN− | Channel 1 inverting input | High-impedance node (1000 GΩ differential resistance); sensitive to PCB leakage and guarding requirements. |
| 1IN+ | Channel 1 non-inverting input | Accepts common-mode voltage from −0.2 V to VS+1.2 V - supports level-shifting and single-supply transducer interfacing. |
| GND | Analog ground reference | Must be tied to low-impedance ground plane; separate from digital ground if mixed-signal layout is used. |
| VDD | Positive supply | Decoupling required: 0.1 μF ceramic capacitor placed ≤2.5 mm from pin; 6.8 μF tantalum recommended for multi-channel stability. |
| 2OUT | Channel 2 output | Independent rail-to-rail output; crosstalk < −40 dB at 100 kHz per Figure 24 - suitable for dual-path signal conditioning. |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; no internal connection to pins 1–4 or 5–6. |
| 2IN+ | Channel 2 non-inverting input | Matches Channel 1 input specs; enables matched dual instrumentation amplifier configurations with external resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers usable output range within 120 mV of VDD/GND at VS = 5 V - eliminates need for level-shifting circuitry in 3.3 V ADC interfaces. |
| 1 pA input bias current | Enables direct coupling to high-impedance sources (e.g., >100 MΩ gas sensors) without significant DC error or drift. |
| 160 kHz bandwidth at 7 μA | Provides 10× higher bandwidth than TLC27L2 at one-third the quiescent current - improves loop response in low-power control systems. |
| −40°C to +125°C operation | Guaranteed performance over full industrial temperature range - avoids derating or thermal compensation in harsh environments. |
| VSSOP-8 (DGK) footprint | 3.0 mm × 3.0 mm body saves >50% PCB area vs. SOIC-8; compatible with standard 0.65 mm pitch reflow profiles (MSL-1). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2382IDGKR | Lower 10 μA IQ, 0.18 V/μs slew rate, 0.06 V/μs min slew at 125°C; same VSSOP-8 package. | Better power efficiency but reduced dynamic response; suited for slower sensor averaging, not fast transient detection. | Select TLV2382IDGKR when quiescent current is primary constraint and bandwidth >100 kHz is unnecessary. |
| TLC27L2CDR | Higher 17 μA IQ, 0.085 V/μs slew rate, 10 mV max VIO, SOIC-8 only; no VSSOP option. | Legacy compatibility with existing SOIC footprints; inferior noise (68 nV/√Hz) and input bias (60 pA). | Choose TLC27L2CDR only for drop-in replacement in mature SOIC-based designs where board rework is prohibited. |
Compared with TLV27L2IDGK, TLV2382IDGKR offers lower power but sacrifices bandwidth and slew rate for ultra-low-IQ operation, while TLC27L2CDR provides pin-compatible SOIC migration at higher power and reduced precision - making TLV27L2IDGK the optimal balance of size, speed, and micropower performance.

FAQ
What is the maximum operating supply voltage for TLV27L2IDGK?
The absolute maximum supply voltage for TLV27L2IDGK is 16.5 V, with recommended operation from 2.7 V to 16 V. Exceeding 16.5 V risks permanent damage. At 16 V, the device maintains rail-to-rail output swing and 160 kHz bandwidth, enabling use in ±8 V dual-supply configurations or high-voltage industrial sensing front-ends where TLV27L2IDGK remains within safe operating limits.
Does TLV27L2IDGK support rail-to-rail input common-mode range?
No, TLV27L2IDGK does not support rail-to-rail input. Its input common-mode voltage range is specified from −0.2 V to VS+1.2 V - meaning it accepts inputs slightly beyond VDD but not down to GND. For true rail-to-rail input capability, TI's TLV2462 or OPA333 families would be required; TLV27L2IDGK is optimized for rail-to-rail *output*, not input.
What is the thermal performance of TLV27L2IDGK in VSSOP-8 package?
The TLV27L2IDGK in DGK (VSSOP-8) package has θJA = 260°C/W on low-K test PCB (no airflow). At TA = 85°C and full 16 V supply, its max power dissipation is ~250 mW. With 14 μA total IQ (7 μA × 2), junction temperature rise is negligible (<1°C), ensuring stable operation without heatsinking in typical ambient conditions.
Can TLV27L2IDGK drive capacitive loads directly?
TLV27L2IDGK is stable with up to 50 pF capacitive load per Figure 16 (phase margin ≥62°). Driving larger loads (e.g., >100 pF) requires isolation resistor (≥100 Ω) between output and capacitance. This limitation is inherent to its BiMOS output stage; unlike fully compensated op-amps, TLV27L2IDGK requires external compensation for heavy capacitive loading in filter or cable-drive applications.
Is TLV27L2IDGK pin-compatible with other VSSOP-8 dual op-amps?
TLV27L2IDGK uses standard VSSOP-8 pinout (1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+) and is pin-compatible with TLV2382IDGKR and TLV2462IDGKR. However, it is *not* pin-compatible with SOIC-8 variants like TLV27L2ID - those require PCB redesign due to different pin 1 location and body dimensions. Always verify pin mapping before substitution.
