Product details
Overview
TLV9304IPWR from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier optimized for cost-sensitive, high-voltage systems. It delivers ±0.5 mV typical input offset voltage, 1-MHz gain-bandwidth product, ±60 mA output drive, 3 V/µs slew rate, and operates from 4.5 V to 40 V supply. It serves as a precision signal conditioner in industrial power supply feedback loops.
For engineers reviewing the TLV9304IPWR datasheet, TLV9304IPWR pinout, TLV9304IPWR application, or TLV9304IPWR equivalent, key selection criteria include its 125°C operating temperature range, robust 40-V differential input tolerance, low 150 µA per-amplifier quiescent current, and compatibility with high-EMI environments such as motor drive power stages and server PSUs.
Technical Context
The TLV9304IPWR implements a patented input protection architecture enabling full 40-V differential input voltage swing without clamping diodes-eliminating transient-induced settling delays and distortion in multiplexed or comparator-mode applications. Its input stage supports common-mode voltages from (V–) – 0.2 V to (V+) – 2 V, and it maintains 110 dB CMRR across –40°C to 125°C.
This quad op amp uses internal EMI filtering to achieve 72 dB rejection at 1 GHz, making it suitable for noisy industrial environments. Its 60° phase margin and stable operation into 20 pF capacitive loads support direct driving of ADC inputs or long traces without external isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (±2.25 V to ±20 V): Enables single-supply operation in 24-V/36-V industrial rails and dual-supply use in precision analog front-ends. |
| Gain-Bandwidth Product | 1 MHz: Supports stable closed-loop gain configurations up to G = 100 at DC–10 kHz, suitable for sensor amplification and PSU error amplifiers. |
| Input Offset Voltage | ±0.5 mV (typ): Delivers ≤10 mV total error in 20-V span measurements without trimming-critical for accurate current sensing in DC/DC converters. |
| Slew Rate | 3 V/µs: Ensures <5 µs 0.1% settling for 10-V steps, enabling fast transient response in overvoltage protection circuits. |
| Output Drive Current | ±60 mA: Drives 2-kΩ loads to rail with <350 mV headroom at 40 V supply-supports direct interfacing with MOSFET gates or optocouplers. |
| Quiescent Current | 150 µA per amplifier: Allows four independent channels in space-constrained designs while maintaining <600 µA total IQ-ideal for always-on monitoring nodes. |
| Operating Temperature | –40°C to +125°C: Qualified for under-hood automotive auxiliary supplies and industrial motor drive control boards. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm), thermally enhanced for high-density PCB layouts in power management modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts signals up to (V–) – 0.2 V and (V+) – 2 V; enables high-side current sensing with bidirectional common-mode range. |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input tolerance up to 40 V allows safe comparator-mode operation without external clamping. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail swing with 3-mV headroom (no load, 40 V supply); drives capacitive loads ≤100 pF directly. |
| V+ (Pin 4) | Positive power supply | Highest potential rail; must be ≥4.5 V above V– for guaranteed operation; decoupling required within 1 cm. |
| V– (Pin 11) | Negative power supply | Lowest potential rail; supports ground-referenced or split-supply configurations; connects to system GND or negative bias. |
| +IN B (Pin 5), –IN B (Pin 6), OUT B (Pin 7) | Channel B inputs/outputs | Electrically identical to Channel A; independent operation enables dual feedback paths in redundant PSU designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9304IDR | SOIC-14 package (8.65 mm × 3.91 mm); higher RθJA (105.5°C/W vs 134.5°C/W for TSSOP); same electrical specs. | Better thermal performance in forced-air-cooled industrial enclosures; less suitable for ultra-dense 4-layer PCBs. | Select TLV9304IDR when board-level airflow exceeds 200 LFM and layout space permits larger footprint. |
| OPA2182IDGKR | Lower offset (±4 µV), lower noise (5.7 nV/√Hz), but higher IQ (530 µA), narrower supply (4.5–36 V), and no 40-V differential input tolerance. | Higher precision in lab-grade instrumentation; unsuitable for comparator-mode or high-dV/dt industrial inputs. | Choose OPA2182IDGKR only when sub-10-µV offset and <10 nV/√Hz noise are mandatory-and input transients are absent. |
Compared with TLV9304IPWR, TLV9304IDR offers superior thermal resistance in ventilated environments but requires more PCB area, while OPA2182IDGKR trades robustness and power efficiency for ultra-low offset-making TLV9304IPWR optimal for cost-sensitive, high-reliability industrial power control where input ruggedness and quiescent current matter most.

FAQ
What is the maximum differential input voltage the TLV9304IPWR can tolerate?
The TLV9304IPWR supports up to 40 V differential input voltage between its inverting and noninverting pins-enabled by its patented input protection architecture. This eliminates need for external clamping diodes and allows safe use in comparator applications or fast-ramping sensor interfaces. The specification is validated across –40°C to 125°C and is not dependent on supply voltage.
Does the TLV9304IPWR require external compensation for unity-gain stability?
No, the TLV9304IPWR is internally compensated for unity-gain stability. It achieves 60° phase margin with 10-kΩ load and 20-pF capacitive load, and exhibits no phase reversal under overload conditions. This allows direct use in voltage-follower configurations without added components-verified in Figure 6-29 and Section 6.7 of the SBOS941D datasheet.
Can the TLV9304IPWR operate from a single 5-V supply?
Yes, the TLV9304IPWR operates from 4.5 V to 40 V single-ended supply (or ±2.25 V to ±20 V dual supply). At 5 V, it delivers rail-to-rail output swing with ≤30 mV headroom into 10-kΩ load and maintains 1-MHz GBW and 33-nV/√Hz input voltage noise-making it suitable for portable test equipment and low-voltage IoT sensor nodes.
How does the EMI rejection performance of TLV9304IPWR benefit industrial designs?
The TLV9304IPWR provides 72 dB electromagnetic interference rejection ratio at 1 GHz-critical for operation near switching power supplies, motor drives, and wireless modules. This integrated EMI filtering prevents corruption of analog signals in building automation controllers and server PSUs without requiring external ferrite beads or RC filters, reducing bill-of-materials and layout complexity.
What is the thermal resistance (RθJA) of the TLV9304IPWR in its TSSOP-14 package?
The TLV9304IPWR in TSSOP-14 (PW) package has a junction-to-ambient thermal resistance (RθJA) of 134.5°C/W, as specified in Section 6.6 of the SBOS941D datasheet. This value assumes standard JEDEC 2S2P board conditions; actual thermal performance improves with copper pour and thermal vias beneath the exposed pad region (though the TSSOP-14 lacks an exposed thermal pad).
