Product details
Overview
TLV9302IDDFR from Texas Instruments is a dual-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 - enabling precision signal conditioning in merchant power supplies and industrial AC-DC converters.
For engineers reviewing the TLV9302IDDFR datasheet, TLV9302IDDFR pinout, TLV9302IDDFR application, or TLV9302IDDFR equivalent, this page provides verified specifications, package mapping to SOT-23-8, functional pin definitions, real-world use cases in PSU feedback loops and motor drive sensing, and two validated alternative op amps with documented technical differences.
Technical Context
The TLV9302IDDFR integrates a patented input protection architecture that supports full 40-V differential input voltage without clamping diodes - eliminating settling delays and distortion in multiplexed or comparator-mode applications. Its input stage tolerates common-mode voltages from (V−) − 0.2 V to (V+) − 2 V and exhibits ±10 pA bias current across temperature.
This dual op amp features robust EMI rejection (72 dB at 1 GHz), 110 dB CMRR at DC, and stable operation with capacitive loads up to 100 pF. It maintains 60° phase margin in unity-gain configuration with 20-pF load, supporting reliable closed-loop performance in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (±2.25 V to ±20 V): Enables direct integration into high-voltage industrial and server power rails without external level-shifting. |
| Input Offset Voltage | ±0.5 mV (typ): Reduces DC error in precision current-sense amplifiers and voltage reference buffers. |
| Gain-Bandwidth Product | 1 MHz: Supports stable closed-loop operation up to ~100 kHz in G = 10 configurations for sensor signal conditioning. |
| Slew Rate | 3 V/µs: Ensures faithful reproduction of fast transients in motor drive current feedback paths. |
| Output Drive Current | ±60 mA: Drives low-impedance loads such as optocoupler LEDs or ADC input RC networks directly. |
| Input Bias Current | ±10 pA (max): Minimizes voltage error across high-value feedback resistors (>1 MΩ) in high-impedance sensor interfaces. |
| EMI Rejection Ratio | 72 dB at 1 GHz: Maintains signal integrity in proximity to Wi-Fi/BT modules or switching power stages without added filtering. |
Pinout & Package
TLV9302IDDFR is packaged in an 8-pin SOT-23-8 (DDF) surface-mount package measuring 2.90 mm × 1.60 mm, rated for operation from –40°C to +125°C and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts high-impedance analog signals up to (V−) − 0.2 V to (V+) − 2 V; supports comparator mode with full 40-V differential swing. |
| −IN A (Pin 2) | Inverting input, Channel A | Used for feedback in inverting configurations; shares same input voltage range and protection as +IN A. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail capable with 3-mV headroom at no load (VS = 40 V); sources/sinks ±60 mA continuously. |
| V− (Pin 4) | Negative power supply | Lowest potential rail; must be connected before applying input signals to avoid latch-up. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent channel input with identical specs and protection as Channel A; enables dual-path sensing. |
| −IN B (Pin 6) | Inverting input, Channel B | Supports independent feedback network; no crosstalk with Channel A per datasheet channel separation >110 dB at DC. |
| OUT B (Pin 7) | Output, Channel B | Matches OUT A performance; allows simultaneous control of two independent circuits (e.g., voltage + current loop). |
| V+ (Pin 8) | Positive power supply | Highest potential rail; supplies both channels; requires local 0.1-µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full dynamic range to downstream ADCs or comparators without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2991IDGKR | Higher GBW (4.5 MHz), lower noise (10.5 nV/√Hz), but higher IQ (1.1 mA/channel) and narrower supply range (2.7–36 V). | Better suited for high-speed active filters or wideband sensor interfaces where bandwidth outweighs power budget constraints. | Select when >1-MHz closed-loop bandwidth is required and 150-µA IQ is not limiting. |
| LM2904BQDR | Lower cost, wider temp range (–40°C to 125°C), but higher offset (±1.5 mV), slower slew (0.3 V/µs), and no rail-to-rail output. | Appropriate for non-critical biasing or slow-settling control loops where precision and speed are secondary to BOM cost. | Choose only if offset error <1.5 mV and output swing >1 V from rail are acceptable in the target application. |
Compared with OPA2991IDGKR and LM2904BQDR, TLV9302IDDFR uniquely balances 1-MHz bandwidth, rail-to-rail output, ±0.5-mV offset, and 150-µA quiescent current in a compact SOT-23-8 package - making it optimal for space-constrained, high-voltage, cost-sensitive industrial power systems requiring precision and low power simultaneously.

FAQ
What is the maximum differential input voltage supported by TLV9302IDDFR?
The TLV9302IDDFR 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 in comparator-mode applications and fast-ramping multiplexed sensor interfaces without signal distortion or extended settling time, as confirmed in Section 7.3.1 of the SBOS941D datasheet.
Does TLV9302IDDFR require external input protection diodes?
No, TLV9302IDDFR does not require external input protection diodes. Its patented input architecture inherently withstands transient overvoltage conditions while maintaining full 40-V differential input capability and low distortion. This eliminates external components, reduces board area, and avoids the settling delays associated with traditional diode-clamped inputs, per Figure 7-1 and Section 7.3.1 of the datasheet.
What is the operating temperature range for TLV9302IDDFR?
TLV9302IDDFR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated across all electrical parameters in the datasheet's Recommended Operating Conditions (Section 6.3) and Thermal Information tables (Sections 6.5–6.6), making it suitable for industrial motor drives and outdoor building automation equipment.
Can TLV9302IDDFR drive capacitive loads directly?
Yes, TLV9302IDDFR is characterized to drive capacitive loads up to 100 pF while maintaining stability and 60° phase margin in unity-gain configuration (Section 6.7, Figure 6-28). For loads >100 pF, a series isolation resistor (e.g., 50 Ω) is recommended to suppress peaking, as shown in Figure 6-26 and Figure 6-27 of the SBOS941D datasheet.
Is TLV9302IDDFR pin-compatible with other dual op amps in SOT-23-8?
No, TLV9302IDDFR uses a non-standard pinout for SOT-23-8: Pin 1 = OUT A, Pin 2 = −IN A, Pin 3 = +IN A, Pin 4 = V−, Pin 5 = +IN B, Pin 6 = −IN B, Pin 7 = OUT B, Pin 8 = V+. This differs from industry-standard dual op amps like LMV358 or OPA2313, which place V+ at Pin 8 but assign inputs and outputs differently. Layout redesign is required for substitution.
