Product details
Overview
TLV2244ID from Texas Instruments is a quad-channel, rail-to-rail input/output micropower 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 TLV2244ID datasheet, TLV2244ID pinout, TLV2244ID application, or TLV2244ID equivalent, this page provides verified electrical specifications, industrial-grade (–40°C to 125°C) thermal performance, SOIC-14 package layout guidance, and validated alternatives for low-power analog front-end design.
Technical Context
The TLV2244ID uses CMOS input stage architecture to achieve picoamp-level input bias currents (≤1000 pA full range), enabling high-impedance sensor interfacing without significant DC error. Its rail-to-rail input common-mode range (0 V to VCC) and output swing (within 180 mV of rails at 50 µA load) support single-supply operation across the full 2.5–12 V range.
Internal compensation ensures stability with capacitive loads up to 100 pF, while phase margin remains ≥60° and gain margin ≥15 dB under all tested supply conditions (2.7 V, 5 V, 12 V). The device exhibits 600 µV typical input offset voltage and 100 dB CMRR at 25°C, supporting precision DC-coupled amplification in multi-channel data acquisition.
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 DC to low-frequency biosignal amplification (ECG, EEG) and thermistor/RTD conditioning. |
| Rail-to-Rail I/O | Input: 0 V to VCC; Output: within 180 mV of rails at 50 µA - maximizes dynamic range in 3.3 V or lower systems. |
| Input Offset Voltage | 600 µV typical (3000 µV max) - supports <1% accuracy in 12-bit ADC front-ends without trimming. |
| Operating Temperature | –40°C to 125°C - qualified for industrial motor control feedback, automotive cabin sensors, and outdoor IoT gateways. |
| Supply Voltage Range | 2.5 V to 12 V - compatible with single-cell Li-ion (3.0–4.2 V), dual-cell alkaline (3.0 V), and 5 V/12 V legacy rails. |
| Common-Mode Rejection | 100 dB typical at 25°C - rejects power supply ripple and EMI in noisy industrial environments. |
Pinout & Package
TLV2244ID is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant footprint, and exposed pad not present. Thermal resistance θJA = 122.6°C/W enables operation up to 125°C ambient with minimal heatsinking.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel; capable of sourcing/sinking ±200 µA into 500 kΩ load. |
| 2 | 1IN– | Inverting input of first channel; high-impedance CMOS node (IIB ≤ 1000 pA). |
| 3 | 1IN+ | Non-inverting input of first channel; rail-to-rail common-mode range (0 V to VCC). |
| 4 | VCC | Positive supply rail; accepts 2.5–12 V; requires local 0.1 µF ceramic decoupling. |
| 5 | 2IN+ | Non-inverting input of second channel; electrically isolated from other channels. |
| 6 | 2IN– | Inverting input of second channel; matched bias current to Pin 2 for common-mode rejection. |
| 7 | 2OUT | Output of second op-amp channel; identical specs to Pin 1. |
| 8 | GND | Analog ground reference; must connect to low-impedance ground plane beneath device. |
| 9 | 3OUT | Output of third channel; fully independent; no crosstalk beyond –60 dB at 1 kHz. |
| 10 | 3IN– | Inverting input of third channel; shares same process-matched characteristics as Pins 2/6. |
| 11 | 3IN+ | Non-inverting input of third channel; rail-to-rail input stage identical to Pins 3/5. |
| 12 | VCC | Shared positive supply for all four channels; single VCC pin reduces PCB routing complexity. |
| 13 | 4IN+ | Non-inverting input of fourth channel; designed for simultaneous multi-sensor buffering. |
| 14 | 4IN– | Inverting input of fourth channel; supports differential configurations with external resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, micropower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | Lower offset (0.39 mV typ), higher GBW (5 kHz), 0.88 µA/channel - but only rated for 0°C to 70°C. | Not suitable for industrial temperature range; better for commercial-grade portable devices requiring tighter DC accuracy. | Select TLV2404IDR when offset voltage is primary constraint and ambient temperature stays below 70°C. |
| LPV821DRXT | Ultra-low power (650 nA/channel), 10 kHz GBW, but single-channel only and 1.8–5.5 V supply range. | Limited to single-ended, low-voltage designs; lacks quad configuration and 12 V capability of TLV2244ID. | Choose LPV821DRXT for space-constrained, sub-3.3 V systems where channel count is secondary to minimum current draw. |
Compared with TLV2404IDR and LPV821DRXT, TLV2244ID uniquely combines quad-channel integration, industrial temperature rating, 12 V operation, and rail-to-rail I/O in a single SOIC-14 package - making it the only option for ruggedized, multi-sensor, battery-operated industrial edge nodes.

FAQ
What is the maximum supply voltage for TLV2244ID?
The absolute maximum supply voltage for TLV2244ID is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operating above 12 V risks exceeding safe power dissipation limits and may degrade long-term reliability. Electrical specifications are guaranteed at 2.7 V, 5 V, and 12 V per the SLOS329C datasheet.
Does TLV2244ID support true rail-to-rail output swing?
Yes, TLV2244ID achieves rail-to-rail output swing: high-level output reaches within 20 mV of VCC at –2 µA load and within 80 mV at –50 µA load; low-level output reaches within 90 mV of GND at +2 µA load and within 260 mV at +50 µA load - confirmed across –40°C to 125°C.
Can TLV2244ID drive capacitive loads without oscillation?
Yes, TLV2244ID is internally compensated for stability with capacitive loads up to 100 pF, maintaining ≥60° phase margin and ≥15 dB gain margin at 2.7 V, 5 V, and 12 V supplies - verified in Figure 24 of the SLOS329C datasheet.
What is the input bias current specification for TLV2244ID?
TLV2244ID has a maximum input bias current of 1000 pA over the full –40°C to 125°C temperature range, with typical value of 100 pA at 25°C. This enables accurate amplification of signals from high-impedance sources such as photodiodes and piezoelectric sensors without significant DC error.
Is TLV2244ID pin-compatible with other TLV224x variants?
No - TLV2244ID uses a 14-pin SOIC package, while TLV2241ID is 5-pin SOT-23 and TLV2242ID is 8-pin MSOP. Pinouts differ significantly across channel count and package types; PCB layout must be redesigned when substituting between TLV2241ID, TLV2242ID, and TLV2244ID.
