Product details
Overview
TLV2241IP from Texas Instruments is a single-channel micropower rail-to-rail input/output operational amplifier in an 8-pin PDIP package, delivering 1 µA per channel supply current, 5.5 kHz gain bandwidth product, and operation from 2.5 V to 12 V. It features 600 µV typical input offset voltage, 100 dB CMRR, and rail-to-rail output swing-ideal for low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2241IP datasheet, TLV2241IP pinout, TLV2241IP application, or TLV2241IP equivalent, this page provides verified electrical specifications, validated DIP-8 pin mapping, real-world use cases in Li-ion–powered instrumentation, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2241IP employs a CMOS input stage enabling ultra-low input bias current (100 pA typ) and high input impedance (>300 MΩ), supporting precision interfacing with mega-ohm-level sensor networks. Its rail-to-rail input common-mode range (0 V to VCC) and output swing (within 180 mV of rails at 50 µA load) ensure full dynamic range utilization in single-supply systems.
Designed for stability with capacitive loads up to 100 pF, it maintains 60° phase margin and 15 dB gain margin. The device operates across –40°C to 125°C (I-suffix), with DC accuracy guaranteed by 3 µV/°C offset drift and 100 V/mV minimum open-loop gain at 2.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1 µA per channel - enables multi-year battery life in always-on environmental sensors. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled transducer amplification and slow-varying process signals. |
| Input Offset Voltage | 600 µV typical - ensures ≤0.02% error in 30 mV thermocouple outputs without trimming. |
| Rail-to-Rail I/O | Input: 0 V to VCC; Output: within 180 mV of rails at 50 µA - maximizes ADC input range in 3.3 V systems. |
| Supply Voltage Range | 2.5 V to 12 V - compatible with Li-ion (3.0–4.2 V), 3.3 V logic, and 9 V industrial rails. |
| CMRR | 100 dB at 25°C - rejects >99.99% of common-mode noise in noisy plant-floor environments. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
Pinout & Package
TLV2241IP uses an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Thermal resistance θJA = 104°C/W enables 1200 mW power dissipation at 25°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal - drives ADC inputs or low-power analog comparators directly. |
| 2 | 1IN– | Inverting input - connects to feedback network in precision inverting configurations. |
| 3 | 1IN+ | Non-inverting input - interfaces with high-impedance pH or RTD sensor bridges. |
| 4 | GND | Analog ground reference - must be tied to clean system ground plane to maintain 100 dB CMRR. |
| 5 | NC | No internal connection - left unconnected; no routing or grounding required. |
| 6 | VCC | Positive supply - accepts 2.5–12 V; decoupling requires 0.1 µF ceramic capacitor placed ≤0.1 inch away. |
| 7 | NC | No internal connection - electrically isolated; no PCB trace needed. |
| 8 | NC | No internal connection - unused pin; standard DIP footprint compatibility only. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail input/output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401CDR | 0.88 µA supply current, 5 kHz GBW, 0.39 mV VIO, 2.5–16 V supply - lower offset but higher current than TLV2241IP. | Better DC accuracy for precision weight scales; less suitable for ultra-long-life battery nodes. | Select TLV2401CDR when offset voltage <400 µV is mandatory and supply current ≤1.5 µA remains acceptable. |
| LPV521MG/NOPB | 322 nA supply current, 15.5 kHz GBW, 170 µV VIO, 1.8–5.5 V supply - lower power and offset, narrower voltage range. | Optimized for 3.3 V IoT edge nodes; incompatible with 9 V or 12 V industrial rails. | Choose LPV521MG/NOPB for new 3.3 V designs prioritizing sub-µA operation and enhanced DC performance. |
Compared with TLV2241IP, TLV2401CDR offers tighter offset at modest current increase, while LPV521MG/NOPB delivers superior micropower and accuracy but sacrifices 2.5–12 V flexibility-making TLV2241IP the optimal balance for legacy industrial systems requiring wide supply tolerance and proven thermal robustness.

FAQ
What is the maximum supply voltage for TLV2241IP?
The absolute maximum supply voltage for TLV2241IP is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operating beyond 12 V risks exceeding safe power dissipation limits and may degrade long-term reliability. Electrical characteristics are fully specified at 2.7 V, 5 V, and 12 V per the SLOS329C datasheet.
Does TLV2241IP support rail-to-rail input and output simultaneously?
Yes, TLV2241IP supports true rail-to-rail input (common-mode range from 0 V to VCC) and rail-to-rail output (swings within 180 mV of both rails at 50 µA load). This dual capability enables full utilization of the supply range in single-supply configurations, such as 3.3 V sensor front-ends interfacing with 12-bit ADCs.
What is the input offset voltage specification for TLV2241IP over temperature?
TLV2241IP has a typical input offset voltage of 600 µV at 25°C, with a maximum of 4500 µV across the full –40°C to 125°C industrial temperature range. Its offset voltage drift is rated at 3 µV/°C, ensuring predictable error growth in temperature-varying environments like automotive cabin modules or outdoor metering units.
Can TLV2241IP drive capacitive loads without instability?
TLV2241IP is stable with capacitive loads up to 100 pF, maintaining ≥60° phase margin and ≥15 dB gain margin per the datasheet's Figure 24 and 25. For loads exceeding 100 pF, external isolation resistance (e.g., 100 Ω in series with the output) is required to preserve stability-critical when driving long PCB traces or ADC input capacitance.
Is TLV2241IP pin-compatible with other devices in the TLV224x family?
No-TLV2241IP (single-channel, 8-pin PDIP) is not pin-compatible with TLV2242 (dual-channel, 8-pin MSOP/SOIC) or TLV2244 (quad-channel, 14-pin TSSOP/SOIC/PDIP). While all share identical electrical behavior and pin function ordering (e.g., IN+, IN–, OUT, VCC, GND), the TLV2241IP's PDIP-8 layout places NC pins at positions 5, 7, and 8, unlike the functional pinouts of multi-channel variants.
