Product details
Overview
TLV2244CDR from Texas Instruments is a quad micropower rail-to-rail input/output operational amplifier optimized for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 1 µA per channel supply current, 5.5 kHz gain bandwidth, ±200 µA output drive, and operates from 2.5 V to 12 V - enabling direct interface with Li-ion batteries and MSP430 microcontrollers in portable medical and environmental monitoring systems.
For engineers reviewing the TLV2244CDR datasheet, TLV2244CDR pinout, TLV2244CDR application, or TLV2244CDR equivalent, this page provides verified electrical specifications, SOIC-14 package terminal mapping, real-world use cases in precision analog front-ends, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The TLV2244CDR implements a CMOS input stage with rail-to-rail common-mode input range (0 V to VCC) and rail-to-rail output swing (within 180 mV of rails at 50 µA load), supporting single-supply operation down to 2.5 V. Its 600 µV typical input offset voltage and 100 dB CMRR at 5 V ensure DC accuracy in high-impedance transducer interfaces.
Designed for stability with capacitive loads up to 100 pF, it achieves 60° phase margin and 15 dB gain margin under unity-gain conditions. The 2 V/ms slew rate and 1.84 ms 0.1% settling time (at 2.7/5 V) support low-frequency precision acquisition without overshoot in slow-sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current / Channel | 1 µA typical - enables >10-year battery life in always-on sensor nodes using CR2032 or coin cells. |
| Gain Bandwidth Product | 5.5 kHz - sufficient for anti-aliasing and post-processing of sub-1 kHz physiological or environmental signals. |
| Input Offset Voltage | 600 µV typical at 25°C - supports 12-bit resolution in 3.3 V ADC systems without trimming. |
| Rail-to-Rail I/O | Input range: 0 V to VCC; Output swing: within 180 mV of rails at 50 µA - maximizes dynamic range in single-supply data loggers. |
| Supply Voltage Range | 2.5 V to 12 V - compatible with Li-ion (3.0–4.2 V), alkaline (2×AA = 3.0 V), and industrial 5/12 V rails. |
| Input Bias Current | 100 pA typical at 25°C - permits use with >10 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| Common-Mode Rejection | 100 dB at 25°C, 5 V - rejects power supply ripple and shared-noise coupling in multi-channel sensor arrays. |
Pinout & Package
TLV2244CDR is supplied in a 14-pin SOIC (D) package with standard JEDEC outline, 1.27 mm pitch, and tape-and-reel packaging (R suffix). Thermal resistance θJA = 176°C/W enables operation up to 70°C ambient without heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives downstream ADC input or filter stage with rail-to-rail swing. |
| 2 | 1IN– | Inverting input of Channel 1 - connects to feedback network in inverting amplifier configurations. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts high-impedance sensor signals with minimal loading. |
| 4 | VCC | Positive supply rail - decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - isolated from Channel 1 inputs to prevent crosstalk in multi-sensor designs. |
| 6 | 2IN– | Inverting input of Channel 2 - used for differential sensing or active filtering with matched resistor networks. |
| 7 | 2OUT | Output of Channel 2 - independent output path avoids inter-channel loading in dual-path signal chains. |
| 8 | GND | Analog ground reference - tied to PCB ground plane with low-inductance connection near device. |
| 9 | 3OUT | Output of Channel 3 - supports three independent sensor channels on single IC (e.g., temperature/humidity/pressure). |
| 10 | 3IN– | Inverting input of Channel 3 - routed separately to minimize noise coupling from digital sections. |
| 11 | 3IN+ | Non-inverting input of Channel 3 - configured as unity-gain buffer for reference voltage distribution. |
| 12 | VCC | Positive supply rail (shared) - same net as Pin 4; requires local decoupling at both ends. |
| 13 | 4IN+ | Non-inverting input of Channel 4 - used for calibration channel or redundant measurement path. |
| 14 | 4OUT | Output of Channel 4 - enables four-channel simultaneous sampling without multiplexing latency. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | 0.88 µA/channel supply current; 5 kHz GBW; 0.39 mV VIO max; 2.5–16 V supply range | Better offset voltage spec (390 µV vs 3000 µV max) but higher supply current at 12 V; reverse-battery protected | Select when lower offset and wider supply range outweigh 12% higher quiescent current in 12 V systems. |
| LPV521MG/NOPB | 322 nA/channel supply current; 15.5 kHz GBW; 170 µV VIO max; 1.8–5.5 V supply range | Ultra-low power and superior DC specs, but limited to ≤5.5 V supply and SC70-5 package (single channel) | Select for single-channel, sub-2 µA applications below 5.5 V where board space and power are critical constraints. |
Compared with TLV2244CDR, TLV2404IDR offers tighter offset and higher supply voltage tolerance but draws more current above 5 V; LPV521MG/NOPB achieves dramatically lower power and better DC accuracy but sacrifices supply range, channel count, and package compatibility.

FAQ
What is the maximum recommended supply voltage for TLV2244CDR?
The absolute maximum supply voltage for TLV2244CDR is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operation above 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 - TLV2244CDR must not be operated continuously at 16.5 V.
Does TLV2244CDR support true rail-to-rail input and output operation?
Yes, TLV2244CDR supports rail-to-rail input (common-mode range from 0 V to VCC) and rail-to-rail output (swing within 180 mV of each rail at 50 µA load). This capability is confirmed across its full 2.5–12 V supply range and 0°C to 70°C temperature range, enabling full utilization of ADC input ranges in single-supply systems.
What is the typical input offset voltage of TLV2244CDR and how does it affect precision designs?
The typical input offset voltage of TLV2244CDR is 600 µV at 25°C, with a maximum of 3000 µV across the full commercial temperature range. In a 3.3 V system driving a 12-bit ADC, this introduces up to ±12 LSB of error at room temperature - acceptable for many sensor interfaces but requiring calibration or external trimming for sub-10-bit accuracy requirements.
Can TLV2244CDR drive capacitive loads without oscillation?
TLV2244CDR is stable with capacitive loads up to 100 pF, achieving 60° phase margin and 15 dB gain margin under unity-gain conditions. For loads exceeding 100 pF, an isolation resistor (≥100 Ω) must be placed in series with the output to maintain stability - this is required in applications driving long PCB traces or ADC input capacitance beyond specification.
What package type and pin count does TLV2244CDR use?
TLV2244CDR uses a 14-pin SOIC (Small Outline Integrated Circuit) package designated as 'D' in TI's ordering nomenclature. It contains four independent op-amp channels with dedicated inputs and outputs, plus shared VCC and GND pins - matching JEDEC MS-012AC standard dimensions and solder-reflow profiles.
