Product details
Overview
TLV2442IPWR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, wide-input-voltage operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, and 600-Ω output drive capability at 5-V supply. Its extended common-mode input range (0 V to 4.25 V min at 5 V) and no phase inversion enable reliable signal conditioning in single-supply sensor interfaces and ADC drivers.
For engineers reviewing the TLV2442IPWR datasheet, TLV2442IPWR pinout, TLV2442IPWR application, or TLV2442IPWR equivalent, key selection criteria include rail-to-rail output swing, input offset voltage ≤950 µV (max at 25°C), low 16 nV/√Hz input noise at 1 kHz, and guaranteed operation from –40°C to 85°C in TSSOP-8 packaging.
Technical Context
The TLV2442IPWR uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ), ultra-low input bias current (1 pA typ), and rail-to-rail output swing without phase inversion near supply rails. Its input stage supports common-mode voltages down to VDD– and up to VDD+ – 1.3 V across temperature.
It features a unity-gain stable architecture with 65° phase margin (RL = 600 Ω, CL = 100 pF), slew rate of 0.75 V/µs (5 V), and large-signal differential voltage amplification ≥0.9 V/mV (min) at 5 V - enabling precision DC-coupled amplification and fast settling (1.5 µs to 0.1%) in closed-loop configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation from 3 V battery systems up to industrial 9 V rails |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables <1 LSB error in 12-bit ADC interfacing with 5 V reference |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - sufficient for anti-aliasing filters and sensor signal conditioning up to ~100 kHz |
| Output Drive Capability | 600-Ω load at 5 V - drives telecom line drivers and SAR ADC input buffers without external buffering |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance piezoelectric or pH sensor front-ends |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V - accepts ground-referenced inputs while maintaining rail-to-rail output swing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Higher GBW (5.5 MHz), lower noise (7 nV/√Hz), but 1.3 mA/ch supply current and narrower common-mode range (0.3 V below VDD) | Better for high-speed filtering; less suitable for ultra-low-power or ground-sensing applications | Select when bandwidth >2 MHz is required and power budget allows +73% current draw |
| MCP6022-I/SN | Lower offset (250 µV max), wider supply range (2.7 V to 6.0 V), but no guaranteed 600-Ω drive and higher input capacitance (12 pF) | Preferred for precision DC measurement; not recommended for driving capacitive ADC inputs or telecom lines | Choose for offset-critical instrumentation where output drive and noise are secondary |
Compared with OPA2340UA and MCP6022-I/SN, TLV2442IPWR uniquely balances rail-to-rail output drive into 600 Ω, ultra-low bias current, and –40°C to 85°C guaranteed operation in a cost-optimized TSSOP-8 package - making it optimal for industrial sensor nodes and portable medical devices requiring robust single-supply performance.

FAQ
What is the maximum operating temperature range for TLV2442IPWR?
The TLV2442IPWR is rated for operation from –40°C to +85°C, as confirmed by its 'I' temperature suffix and characterization in the SLOS169H datasheet. This range is validated across all electrical parameters including input offset voltage, CMRR, and output drive capability - making it suitable for industrial control cabinets and outdoor sensor enclosures without derating.
Does TLV2442IPWR support true rail-to-rail input operation?
No, TLV2442IPWR provides rail-to-rail *output* swing only. Its common-mode input voltage range extends from VDD– to VDD+ – 1.3 V at 5 V (0 V to 4.25 V min), which exceeds standard CMOS op-amps but does not reach the positive rail. The device explicitly avoids phase inversion when inputs approach either rail - a key differentiator versus non-rail-to-rail input alternatives.
Can TLV2442IPWR drive a 1000-pF capacitive load stably?
TLV2442IPWR is characterized for stability with 100 pF capacitive load (65° phase margin, RL = 600 Ω). Driving 1000 pF directly risks oscillation; TI recommends adding a series resistor (≥100 Ω) between output and capacitive load or using an external isolation buffer. This limitation is documented in Figure 48 (phase margin vs. load capacitance) of the SLOS169H datasheet.
What is the typical input offset voltage drift over temperature for TLV2442IPWR?
The TLV2442IPWR has a typical input offset voltage temperature coefficient (αVIO) of 2 µV/°C, as specified in the Electrical Characteristics table for VDD = 5 V. Over its full operating range (–40°C to +85°C), this results in ≤250 µV total drift - well within the 950 µV maximum offset spec at 25°C, confirming suitability for precision DC-coupled applications.
Is TLV2442IPWR pin-compatible with other devices in the TLV244x family?
Yes, TLV2442IPWR shares identical pinout and footprint with TLV2442CDR, TLV2442AIPW, and TLV2442QPW - all dual op-amps in TSSOP-8 (PW) package. Differences lie in temperature grade (I = –40°C to 85°C), input offset voltage (A-grade = ≤950 µV), and qualification level (Q = automotive), not pin assignment or electrical interface.
