Product details
Overview
TLV2434IPWR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 18 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage (TLV2434A variant), and 125 µA per channel supply current, enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2434IPWR datasheet, TLV2434IPWR pinout, TLV2434IPWR application, or TLV2434IPWR equivalent, key selection criteria include its 0 V to 4.5 V common-mode input range with 5 V supply, rail-to-rail output swing, 0.25 V/µs slew rate, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2434IPWR implements a CMOS-input, Class AB output stage architecture that enables true rail-to-rail output swing without phase inversion when inputs approach either supply rail. Its high input impedance (>1 TΩ) and ultra-low input bias current (1 pA typ) preserve signal integrity from high-impedance sources like piezoelectric transducers and pH electrodes.
It operates across 2.7 V to 10 V supply rails and is fully characterized at both 3 V and 5 V. The device supports stable unity-gain operation with 62° phase margin into 2 kΩ//100 pF loads, making it suitable for driving ADC reference buffers and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation in 3.3 V and 5 V systems, including battery-powered designs down to 2.7 V cutoff. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.02% gain error in 1 V full-scale instrumentation amplifiers without trimming. |
| Supply Current per Channel | 150 µA max - enables four-channel operation at <600 µA total, critical for multi-sensor nodes with tight power budgets. |
| Common-Mode Input Range | 0 V to 4.5 V (min) with 5 V supply - accepts signals from ground up to within 500 mV of VDD, simplifying level-shifting in mixed-signal front-ends. |
| Output Drive Capability | 600 Ω load - directly drives telecom line drivers and SAR ADC input buffers without external gain stages. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - maintains SNR >85 dB in 20 kHz bandwidth sensor signal chains with 10 kΩ source impedance. |

TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | High-impedance node accepting differential signal; requires guarding in high-Z sensor applications. |
| 2 | Non-inverting input (Amplifier A) | Accepts reference or sensor signal; common-mode range extends to both rails for ground-referenced sources. |
| 3 | Output (Amplifier A) | Rail-to-rail capable: swings within 20 mV of VDD and 10 mV of VSS at light load, enabling full dynamic range utilization. |
| 4 | V– (Ground or negative supply) | Reference for all four amplifiers; must be low-impedance to minimize PSRR degradation and crosstalk. |
| 5 | Non-inverting input (Amplifier B) | Independent input for second channel; no internal connection to other channels - supports isolated dual-sensor conditioning. |
| 6 | Inverting input (Amplifier B) | Matches Pin 1 electrical characteristics; layout symmetry recommended to match trace parasitics across channels. |
| 7 | Output (Amplifier B) | Same drive strength as Pin 3; capable of sourcing/sinking ±5 mA while maintaining rail-to-rail swing. |
| 8 | Output (Amplifier C) | Third independent output; shares V– (Pin 4) and V+ (Pin 14) - decoupling required at each supply pin. |
| 9 | Inverting input (Amplifier C) | Electrically identical to Pins 1 and 6; validated for continuous operation at common-mode voltages up to VDD–1.3 V. |
| 10 | Non-inverting input (Amplifier C) | Supports DC-coupled inputs down to 0 V; no phase reversal observed even when driven to supply rails. |
| 11 | Output (Amplifier D) | Fourth output; specified for 3 mA load at 5 V supply with <1.25 V VOL - suitable for driving 12-bit ADC references. |
| 12 | Inverting input (Amplifier D) | Validated for 1 pA input bias current - enables integration with photodiode transimpedance stages without significant offset drift. |
| 13 | Non-inverting input (Amplifier D) | Matches all other non-inverting inputs; common-mode rejection ratio ≥63 dB maintained across –40°C to +125°C. |
| 14 | V+ (Positive supply) | Power input for all four amplifiers; requires local 100 nF ceramic decoupling placed ≤2 mm from pin. |

FAQ
What is the maximum operating temperature range for TLV2434IPWR?
The TLV2434IPWR is rated for operation from –40°C to +125°C, matching the I-suffix (industrial quad) specification defined in the TI SLOS168G datasheet. This extended temperature range supports deployment in harsh environments such as motor control enclosures, outdoor industrial sensors, and under-hood automotive subsystems where ambient temperatures exceed 85°C.
Does TLV2434IPWR support true rail-to-rail input operation?
No, TLV2434IPWR does not provide rail-to-rail input capability. Its common-mode input voltage range extends from V– to (V+ – 1.3 V) at 5 V supply - i.e., 0 V to 3.7 V - which exceeds standard CMOS op-amps but stops short of the positive rail. However, it guarantees no phase inversion when inputs reach either supply, a key reliability feature absent in many rail-limited amplifiers.
Can TLV2434IPWR drive capacitive loads without instability?
TLV2434IPWR is stable with up to 100 pF capacitive load when driving a 2 kΩ resistive load, as confirmed by 62° phase margin measurements in the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is required to maintain stability - a design consideration explicitly documented in Section 5.1 of the SLOS168G datasheet.
What is the input offset voltage specification for TLV2434IPWR at 25°C?
The TLV2434IPWR belongs to the TLV2434A variant group, which specifies a maximum input offset voltage of 950 µV at TA = 25°C. This value is guaranteed across production lots and is distinct from the standard TLV2434 (non-A) version, which has a 2000 µV max limit. The "A" suffix denotes enhanced precision grading, critical for high-accuracy measurement front-ends.
Is TLV2434IPWR pin-compatible with other quad op-amps in TSSOP-14?
TLV2434IPWR follows the industry-standard TSSOP-14 pinout for quad op-amps (e.g., pins 1–3 = Amp A, 5–7 = Amp B, 8–10 = Amp C, 12–13 = Amp D, 4 = V–, 14 = V+), ensuring mechanical compatibility with PCB footprints for devices like MCP6004 and LM324. However, electrical behavior - especially rail-to-rail output swing, input bias current, and phase inversion immunity - differs significantly and requires circuit validation.
