Product details
Overview
TLV2242ID from Texas Instruments is a dual-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, ±100 µV typical input offset voltage (at 25°C), and operates from 2.5 V to 12 V - enabling direct compatibility with Li-ion cells and MSP430 microcontrollers in portable medical and environmental monitoring systems.
For engineers reviewing the TLV2242ID datasheet, TLV2242ID pinout, TLV2242ID application, or TLV2242ID equivalent, this page provides verified package mapping (8-pin MSOP-DGK), confirmed industrial-grade temperature range (–40°C to 125°C), rail-to-rail I/O performance at 2.7 V/5 V/12 V, and validated alternative options for low-power precision amplification where quiescent current < 2 µA/channel and input bias current < 1 pA are critical selection criteria.
Technical Context
The TLV2242ID uses CMOS input stage architecture to achieve sub-picoampere input bias current (100 pA typ. at 25°C) and rail-to-rail common-mode input range (0 V to VCC). Its output stage supports rail-to-rail swing with ±200 µA drive capability into high-impedance loads, maintaining stability with capacitive loads up to 100 pF without external compensation.
Designed for single-supply operation, it features 100 dB CMRR and 100 V/mV open-loop gain at 2.7 V, with guaranteed performance across –40°C to 125°C. The device exhibits 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, CL = 100 pF), confirming robust small-signal stability in high-impedance feedback networks.
Key Specifications

| 2 | 1IN– | Inverting input of first channel - accepts differential signals with 0 V to VCC common-mode range |
| 3 | 1IN+ | Non-inverting input of first channel - used for unity-gain buffers or precision reference buffering |
| 4 | GND | Analog ground reference - must be connected to low-noise system ground plane |
| 5 | VCC | Positive supply rail - accepts 2.5 V to 12 V; requires local 0.1 µF ceramic decoupling |
| 6 | 2IN+ | Non-inverting input of second channel - independent of first channel for dual-sensor interfaces |
| 7 | 2IN– | Inverting input of second channel - supports differential input configurations with matched layout |
| 8 | 2OUT | Output of second op-amp channel - electrically isolated from 1OUT for dual-path signal processing |

FAQ
What is the maximum recommended supply voltage for TLV2242ID?
The absolute maximum supply voltage for TLV2242ID is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operating at 12 V is fully characterized and supported across the full industrial temperature range (–40°C to 125°C), with electrical specifications guaranteed at 2.7 V, 5 V, and 12 V per the datasheet. Exceeding 12 V may compromise long-term reliability.
Does TLV2242ID support true rail-to-rail input and output operation?
Yes, TLV2242ID supports true rail-to-rail input and output operation. Its input common-mode voltage range extends from 0 V to VCC, and its output can swing within 180 mV of both rails at 50 µA load - verified at 2.7 V, 5 V, and 12 V supplies. This enables full utilization of supply headroom in low-voltage systems such as 3.3 V or single Li-ion (3.0–4.2 V) applications.
What is the input bias current specification for TLV2242ID at 125°C?
At 125°C, the input bias current for TLV2242ID is specified at a maximum of 1000 pA (1 nA) across the full industrial temperature range (–40°C to 125°C). At 25°C, it is typically 100 pA. This ultra-low bias current enables accurate interfacing with high-impedance sources like pH electrodes or photodiode transimpedance circuits without significant error.
Can TLV2242ID drive capacitive loads without instability?
TLV2242ID is stable with capacitive loads up to 100 pF when driving into RL = 500 kΩ, as confirmed by 60° phase margin and 15 dB gain margin in the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 100 Ω in series with output) is recommended. The device does not require internal compensation adjustments for standard sensor interface applications.
Is TLV2242ID pin-compatible with other devices in the TLV224x family?
TLV2242ID in the 8-pin MSOP (DGK) package shares identical pinout with TLV2242CD and TLV2242IP, but is not pin-compatible with TLV2241 (5-pin SOT-23) or TLV2244 (14-pin TSSOP). All TLV2242 variants (CD, ID, IP) use the same 1OUT/1IN–/1IN+/GND/VCC/2IN+/2IN–/2OUT pin assignment, ensuring drop-in replacement within the dual-channel variant group.
