Product details
Overview
TLV2242IDR from Texas Instruments is a dual-channel, rail-to-rail input/output micropower operational amplifier optimized for ultra-low supply current (1 µA per channel), 2.5 V to 12 V single-supply operation, and industrial temperature range (–40°C to 125°C). It delivers 5.5 kHz unity-gain bandwidth, 600 µV typical input offset voltage, and rail-to-rail output swing into high-impedance loads - ideal for battery-powered sensor signal conditioning in portable instrumentation.
For engineers reviewing the TLV2242IDR datasheet, TLV2242IDR pinout, TLV2242IDR application, or TLV2242IDR equivalent, key selection criteria include its 1-µA/channel quiescent current, guaranteed rail-to-rail I/O performance at 2.7 V, low input bias current (<500 pA), CMRR of 100 dB at 25°C, and MSOP-8 package compatibility with space-constrained industrial sensing nodes.
Technical Context
The TLV2242IDR employs CMOS input-stage architecture enabling femtoampere-level input bias currents and rail-to-rail common-mode input voltage range (0 V to VCC). Its internal compensation ensures stable unity-gain operation with capacitive loads up to 100 pF while maintaining ≥60° phase margin.
Designed for single-supply systems, it operates down to 2.5 V - matching Li-ion battery minimum voltage and MSP430 MCU logic levels - and supports split-supply configurations (±1.25 V to ±6 V). Electrical specifications are fully characterized at 2.7 V, 5 V, and 12 V across the full –40°C to 125°C industrial temperature range.
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. |
| Input Offset Voltage | 600 µV typical at 25°C - supports accurate DC-coupled amplification of mV-level thermocouple or bridge outputs. |
| Unity-Gain Bandwidth | 5.5 kHz - sufficient for anti-aliasing and low-frequency sensor signal conditioning (e.g., strain gauges, RTDs). |
| Rail-to-Rail Output Swing | Within 10 mV of rails at IOL/IOH = 2 µA - maximizes dynamic range when interfacing with 8–12-bit ADCs. |
| Common-Mode Rejection | 100 dB at 25°C - rejects power supply ripple and EMI in noisy industrial environments. |
| Input Bias Current | 100 pA typical at 25°C - permits use with >10 MΩ gain-setting resistors without significant offset drift. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive sensors, motor control feedback, and industrial PLC I/O modules. |
Pinout & Package
TLV2242IDR is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad (non-electrical). The package supports reflow soldering per JEDEC J-STD-020 and achieves θJA = 259.9°C/W on standard PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives high-impedance loads directly; rail-to-rail swing supports full-scale ADC input. |
| 2 | 1IN– | Inverting input of Channel 1 - high-impedance node; sensitive to layout-induced noise; requires short trace routing. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from 0 V to VCC; enables true single-supply sensor interface. |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane; separate from digital ground if mixed-signal PCB. |
| 5 | VCC | Positive supply rail - decouple with 0.1 µF ceramic capacitor placed ≤2 mm from pin; supports 2.5–12 V operation. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - independent of Channel 1; enables dual-sensor monitoring or differential pair configuration. |
| 7 | 2IN– | Inverting input of Channel 2 - electrically isolated from Channel 1 inputs; allows independent gain/feedback networks. |
| 8 | 2OUT | Output of Channel 2 - identical AC/DC performance to Pin 1; supports dual-channel signal path without cross-talk degradation. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 1 µA per channel supply current enables multi-year operation on primary batteries in wireless sensor transmitters. |
| Rail-to-rail I/O | Input common-mode range spans 0 V to VCC; output swings within 10 mV of rails - preserves full ADC resolution. |
| Low input bias current | 100 pA typical at 25°C - eliminates significant error from leakage through high-value feedback resistors (>10 MΩ). |
| Industrial temperature grade | Specified from –40°C to 125°C - suitable for engine control units, industrial motor drives, and outdoor environmental monitors. |
| Low offset voltage drift | 3 µV/°C - maintains accuracy over wide ambient temperature swings without recalibration in field-deployed equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2242CDR | Commercial temperature grade (0°C to 70°C); otherwise identical electrical specs and pinout. | Restricted to indoor, climate-controlled environments - not suitable for automotive or industrial edge deployments. | Select TLV2242CDR only for cost-sensitive consumer electronics where ambient temperature remains <70°C. |
| LPV821DRX | Lower supply current (650 nA/ch), higher GBW (13 kHz), but narrower supply range (1.6–5.5 V) and no 125°C rating. | Optimized for sub-5-V battery systems (e.g., wearables); lacks high-voltage capability and extended temperature support. | Choose LPV821DRX when ultra-low power dominates and supply is fixed at 3.3 V; retain TLV2242IDR for 12-V or wide-temp designs. |
Compared with TLV2242CDR and LPV821DRX, the TLV2242IDR uniquely balances ultra-low power (1 µA), wide supply (2.5–12 V), and industrial temperature operation - making it the only option for battery-backed 12-V industrial sensors requiring 125°C qualification.

FAQ
What is the maximum supply voltage for TLV2242IDR?
The absolute maximum supply voltage for TLV2242IDR 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. All electrical specifications in the datasheet are guaranteed within the 2.5–12 V range, with characterization points at 2.7 V, 5 V, and 12 V.
Does TLV2242IDR support true rail-to-rail input at 2.5 V supply?
Yes, TLV2242IDR supports rail-to-rail input common-mode range (0 V to VCC) down to 2.5 V supply. At VCC = 2.5 V, the input stage remains fully functional across the entire 0–2.5 V range, enabling direct interfacing with low-voltage sensors and microcontrollers such as the MSP430 - a key design feature confirmed in the "Recommended Operating Conditions" table.
What is the typical input bias current of TLV2242IDR at 125°C?
The typical input bias current of TLV2242IDR is 100 pA at 25°C and increases to ≤1000 pA across the full –40°C to 125°C industrial temperature range, as specified in the "Electrical Characteristics" table under IIB for TLV224xI devices. This remains sufficiently low to avoid significant errors in high-impedance sensor interfaces even at maximum operating temperature.
Can TLV2242IDR drive capacitive loads without oscillation?
TLV2242IDR is internally compensated for unity-gain stability with capacitive loads up to 100 pF, maintaining ≥60° phase margin per Figure 24. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended. The device's low slew rate (2 V/ms) inherently limits high-frequency instability, making it robust in typical sensor-buffering configurations.
Is TLV2242IDR pin-compatible with other packages in the TLV224x family?
No - TLV2242IDR uses the 8-pin MSOP (DGK) package, while TLV2242 variants in SOIC (D) or PDIP (P) packages share identical pinout but differ in thermal and parasitic characteristics. The SOT-23 (TLV2241) and TSSOP (TLV2244) variants have different pin counts and layouts. Always verify mechanical and thermal design requirements when substituting packages, even within the same family.
