Product details
Overview
TLV2244IDR 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.
For engineers reviewing the TLV2244IDR datasheet, TLV2244IDR pinout, TLV2244IDR application, or TLV2244IDR equivalent, key selection criteria include its guaranteed rail-to-rail I/O performance at 2.7 V, 600 µV typical input offset voltage, 100 dB CMRR, and industrial-grade (–40°C to 125°C) operation in SOIC-14 packaging.
Technical Context
The TLV2244IDR implements a CMOS input stage with p-channel differential pairs, enabling femtoampere-level input bias currents (<500 pA) and compatibility with high-impedance sensor sources up to megaohm range. Its internal compensation ensures stable unity-gain operation with capacitive loads up to 100 pF.
It supports single-supply operation down to 2.5 V while maintaining rail-to-rail output swing within 180 mV of each rail at 50 µA load and full common-mode input range (0 V to VCC). DC accuracy is preserved across temperature via low 3 µV/°C offset drift and 100 V/mV minimum open-loop gain at 2.7 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | Lower 0.88 µA/channel supply current; 5 kHz GBW; 0.39 mV VIO max | Better DC accuracy but reduced drive strength (±100 µA); not rated for 125°C | Select when ultra-low offset and sub-1 µA consumption outweigh temperature range needs |
| LP324DR | Higher 20 µA/channel supply current; 100 kHz GBW; 3 mV VIO max; no rail-to-rail output | Higher speed and drive, but incompatible with 2.5–3.3 V battery systems due to limited output swing | Select only for cost-sensitive industrial controls where 5 V supply and moderate accuracy suffice |
Compared with TLV2244IDR, TLV2404IDR offers tighter offset and lower current but sacrifices high-temperature operation and output drive, while LP324DR trades micropower capability for speed and cost - making TLV2244IDR the optimal balance for battery-powered precision analog systems requiring extended temperature coverage.

FAQ
What is the maximum supply voltage for TLV2244IDR?
The absolute maximum supply voltage for TLV2244IDR 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 specifications are fully characterized at 2.7 V, 5 V, and 12 V, with guaranteed rail-to-rail I/O performance across this range. TLV2244IDR must never be operated beyond 16.5 V, even momentarily.
Does TLV2244IDR support true rail-to-rail output swing?
Yes, TLV2244IDR delivers true rail-to-rail output swing: at 50 µA load, the output reaches within 180 mV of both VCC and GND across the full temperature range (–40°C to 125°C). At lighter loads (2 µA), it achieves 150 mV from each rail. This capability enables full utilization of the supply voltage in low-voltage systems such as 3.3 V or single-cell Li-ion designs, maximizing signal-to-noise ratio without external level-shifting circuitry.
Can TLV2244IDR operate from a 2.5-V supply?
Yes, TLV2244IDR is fully specified and functional at 2.5 V - the minimum recommended supply voltage. At 2.5 V, it maintains rail-to-rail input common-mode range (0 V to 2.5 V), rail-to-rail output swing (within 260 mV of rails at 50 µA), and 1 µA/channel supply current. This makes TLV2244IDR compatible with emerging ultra-low-voltage microcontrollers and energy-harvesting systems where supply rails dip below 3 V.
What is the input bias current specification for TLV2244IDR?
The input bias current for TLV2244IDR is 100 pA typical at 25°C and ≤500 pA over the full industrial temperature range (–40°C to 125°C). This ultra-low value results from its CMOS input stage and enables accurate amplification of signals from high-impedance sources such as pH electrodes, photodiodes, and piezoelectric sensors without significant voltage drop across source impedances up to 10 MΩ.
Is TLV2244IDR pin-compatible with other devices in the TLV224x family?
No, TLV2244IDR is not pin-compatible with TLV2241 or TLV2242 due to differing channel counts and package footprints: TLV2241 uses 5-pin SOT-23 or 8-pin SOIC, TLV2242 uses 8-pin MSOP or SOIC, while TLV2244IDR uses 14-pin SOIC. However, all TLV224x devices share identical electrical behavior per channel, allowing schematic reuse of biasing and feedback networks when migrating between variants - only PCB layout and routing require revision.
