Product details
Overview
TLV9302IPWR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for cost-sensitive 40-V systems. It delivers ±0.5 mV offset voltage, ±2 µV/°C drift, 1-MHz gain-bandwidth, 3 V/µs slew rate, and 150 µA per amplifier quiescent current. It operates from 4.5 V to 40 V (±2.25 V to ±20 V) and supports industrial AC-DC and merchant DC/DC power supply monitoring.
For engineers reviewing the TLV9302IPWR datasheet, TLV9302IPWR pinout, TLV9302IPWR application, or TLV9302IPWR equivalent, this page provides verified electrical specifications, package-confirmed pin functions, dual-channel layout considerations, and real-world use cases in high-voltage power conversion and motor drive feedback loops.
Technical Context
The TLV9302IPWR implements a patented input protection architecture enabling full 40-V differential input voltage swing without clamping diodes-critical for comparator-like behavior and fast-ramping signal acquisition. Its robust EMI rejection (72 dB at 1 GHz) stems from integrated on-die filtering, reducing sensitivity to RF noise in mixed-signal power supplies.
This dual op amp features MUX-friendly inputs with rail-to-rail common-mode range, ±60 mA output drive, and stable operation into 100-pF capacitive loads. It is specified across –40°C to 125°C and supports single-supply (4.5–40 V) or split-supply (±2.25 V to ±20 V) configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (or ±2.25 V to ±20 V): Enables direct interface with 24-V and 36-V industrial rails without level-shifting. |
| Input Offset Voltage | ±0.5 mV (typ): Ensures <100 µV error in 200-mV current-sense shunt amplification at room temperature. |
| Offset Drift | ±2 µV/°C (max): Limits total offset shift to <340 µV over –40°C to 125°C ambient, critical for precision feedback stability. |
| Gain-Bandwidth Product | 1 MHz: Supports stable closed-loop gain ≥10 up to 100 kHz, suitable for voltage loop compensation in DC/DC controllers. |
| Slew Rate | 3 V/µs: Allows full-scale 10-V output transitions in ≤3.3 µs, meeting transient response requirements in servo power supplies. |
| Output Drive | ±60 mA (short-circuit): Sustains 2-kΩ load drive at rail-to-rail swing, eliminating need for external buffers in sensor interface stages. |
| Quiescent Current | 150 µA per amplifier: Enables low-power biasing in always-on monitoring circuits without thermal penalty. |
Pinout & Package
TLV9302IPWR is housed in an 8-pin TSSOP (PW) package measuring 4.40 mm × 3.00 mm, optimized for high-density PCB layouts in power supply control 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; supports rail-to-rail common-mode range for direct connection to shunt resistors or DAC outputs. |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input voltage tolerance up to 40 V enables safe use as comparator during overvoltage transients. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail swing with 50 mV headroom at 10 kΩ load ensures full dynamic range utilization in 3.3-V or 5-V ADC front-ends. |
| V– (Pin 4) | Negative (lowest) power supply | Reference node for dual-supply operation; accepts ground or negative rail-must be decoupled with 100 nF ceramic capacitor. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent channel allows simultaneous monitoring of input and output voltages in isolated DC/DC converters. |
| –IN B (Pin 6) | Inverting input, Channel B | Same robust input architecture as Channel A-no external clamping required even under fast 10-V/µs transients. |
| OUT B (Pin 7) | Output, Channel B | Delivers identical AC/DC performance to OUT A; enables dual-path signal conditioning without cross-talk (–110 dB at 1 kHz). |
| V+ (Pin 8) | Positive (highest) power supply | Supports up to 40 V; internal regulation maintains consistent biasing across full supply range-no external LDO needed. |
Key Features
| Feature | Design Value |
|---|---|
| Patented input protection | Eliminates external clamping diodes while supporting 40-V differential input-reduces BOM count and avoids settling-time penalties in multiplexed sensor arrays. |
| Rail-to-rail output | Delivers 50 mV headroom at 10 kΩ load across full temperature range-maximizes ADC resolution in 12-bit and 16-bit data acquisition systems. |
| EMI rejection | 72 dB at 1 GHz suppresses cellular/WiFi interference in server PSU control boards without added ferrite beads or shielding. |
| MUX-friendly inputs | Common-mode range extends to supply rails (V– – 0.2 V to V+ – 2 V), enabling direct connection to analog switches without level-shifting circuitry. |
| High output current | ±60 mA sourcing/sinking capability drives 2-kΩ loads directly-removes need for buffer stages in voltage reference distribution networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Lower supply range (3–32 V), higher offset (±2 mV), no 40-V differential input tolerance. | Limited to ≤24-V systems; unsuitable for fast transient immunity or high-accuracy shunt sensing. | Choose LM358DR only for legacy 5-V/12-V designs where cost is primary and 40-V robustness is unnecessary. |
| OPA2991IDR | Higher precision (±125 µV offset), lower noise (10.5 nV/√Hz), but higher IQ (560 µA) and narrower supply (2.7–36 V). | Better for low-noise instrumentation; less optimal for battery-constrained or wide-input-range power monitoring. | Select OPA2991IDR when sub-200-µV offset and <12 nV/√Hz noise are mandatory-accept higher power and reduced HV margin. |
Compared with LM358DR and OPA2991IDR, TLV9302IPWR uniquely balances 40-V differential input tolerance, ±0.5-mV offset, and 150-µA quiescent current-making it the only dual op amp qualified for cost-sensitive, high-voltage industrial power conversion where both robustness and precision are required.

FAQ
What is the maximum differential input voltage specification for TLV9302IPWR?
The TLV9302IPWR supports a maximum differential input voltage of 40 V-enabled by its patented input protection architecture that eliminates conventional clamping diodes. This allows safe operation as a comparator or in high-slew-rate signal paths without external limiting components. The specification is confirmed in Section 6.1 Absolute Maximum Ratings and validated in Figure 7-1 of the SBOS941D datasheet.
Does TLV9302IPWR require external input protection diodes?
No, TLV9302IPWR does not require external input protection diodes due to its patented internal architecture, which handles fast transients without signal distortion or settling delay. This is explicitly stated in Section 7.3.1 and demonstrated in Figure 7-2 of the SBOS941D datasheet. External diodes would degrade performance and are unnecessary for operation within absolute maximum ratings.
What is the operating temperature range for TLV9302IPWR?
TLV9302IPWR is fully specified from –40°C to +125°C ambient temperature, with all key parameters-including offset voltage, CMRR, and quiescent current-guaranteed across this range. This is documented in Section 6.3 Recommended Operating Conditions and validated in Figures 6-3 through 6-23 of the SBOS941D datasheet.
Can TLV9302IPWR drive capacitive loads without instability?
Yes, TLV9302IPWR is characterized to drive up to 100 pF capacitive loads with stable phase margin (>60°) and minimal overshoot, as shown in Figures 6-26 through 6-28 of the SBOS941D datasheet. For loads >100 pF, a small series resistor (e.g., 50 Ω) at the output is recommended to maintain stability-no external compensation network is required for typical PCB trace capacitance.
Is TLV9302IPWR pin-compatible with other dual op amps in TSSOP-8 packages?
TLV9302IPWR uses the industry-standard TSSOP-8 pinout defined in Table 5-2 of the SBOS941D datasheet, matching common dual op amp footprints including LM358, TL072, and OPA234. However, functional compatibility requires verification of supply range, input/output swing, and bandwidth-TLV9302IPWR's 40-V differential input and rail-to-rail output exceed those of most legacy parts.
