Product details
Overview
TLV9352IPWR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for cost-sensitive, high-voltage industrial systems. It delivers 3.5-MHz gain-bandwidth, 20 V/µs slew rate, ±350 µV max input offset voltage, and operates from 4.5 V to 40 V supply - enabling precision signal conditioning in AC motor drive power stages and programmable logic controllers.
For engineers reviewing the TLV9352IPWR datasheet, TLV9352IPWR pinout, TLV9352IPWR application, or TLV9352IPWR equivalent, key selection criteria include its MUX-friendly inputs (differential input range to supply rails), robust 110 dB CMRR, low 15 nV/√Hz noise at 1 kHz, ±10 pA input bias current, and EMI/RFI-filtered inputs for noisy industrial environments.
Technical Context
The TLV9352IPWR integrates two independent amplifiers in a single SOIC-8 package, each featuring fully differential input stages capable of accepting common-mode voltages extending to both supply rails - eliminating need for level-shifting in multiplexer-based sensor front-ends. Its architecture supports open-loop comparator operation without external clamping diodes.
It employs a high-slew-rate, low-noise output stage delivering ±60 mA short-circuit current and rail-to-rail swing within 10 mV of rails under no-load conditions. The device maintains stable operation with capacitive loads up to 300 pF and exhibits 60° phase margin at unity gain with 10-kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 3.5 MHz - enables stable closed-loop operation up to ~300 kHz with G = 10, suitable for fast feedback loops in servo control. |
| Slew rate | 20 V/µs - supports clean 10-V step response in ≤5 µs (0.01% settling), critical for pulse-width modulation (PWM) monitoring. |
| Input offset voltage | ±0.35 mV (max) - ensures <1 LSB error in 12-bit ADC interfaces over temperature, reducing calibration overhead. |
| Common-mode rejection | 110 dB (typ) - suppresses supply ripple and ground noise in high-side current sensing across wide voltage ranges. |
| Supply voltage range | 4.5 V to 40 V - accommodates direct connection to 24-V industrial buses and 36-V battery systems without regulators. |
| Quiescent current | 650–800 µA per amplifier - enables dual-amplifier signal chain operation below 1.6 mA total, supporting low-power PLC I/O modules. |
| EMI rejection ratio | ≥60 dB up to 100 MHz - mitigates RF interference from variable-frequency drives and switching power supplies. |
Pinout & Package
TLV9352IPWR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, rated for operation from –40°C to +125°C and compatible with standard surface-mount reflow profiles.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives loads down to 2 kΩ while maintaining <250 mV headroom at 40 V supply. |
| 2 | IN– A | Inverting input, channel A - accepts common-mode voltages from (V–) – 0.2 V to (V+) – 2 V; MUX-friendly for unbuffered analog switches. |
| 3 | IN+ A | Noninverting input, channel A - identical common-mode range as IN– A; enables true rail-to-rail differential input operation. |
| 4 | V– | Negative supply terminal - shared reference for both amplifiers; must be connected to lowest system potential (e.g., GND or –15 V). |
| 5 | IN+ B | Noninverting input, channel B - electrically isolated from channel A; supports independent signal paths in dual-sensor systems. |
| 6 | IN– B | Inverting input, channel B - same MUX-friendly voltage range as channel A inputs; allows simultaneous sampling of two signals. |
| 7 | OUT B | Amplifier B output - fully independent output stage; supports separate feedback networks and load isolation. |
| 8 | V+ | Positive supply terminal - accepts up to 40 V; powers both amplifiers; decoupling capacitor required near pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly inputs | Differential input voltage range extends to supply rails - eliminates external clamping in multiplexed sensor arrays and reduces component count. |
| Rail-to-rail output | Swings within 10 mV of rails at no load - maximizes dynamic range in single-supply data acquisition systems. |
| High output current | ±60 mA short-circuit capability - directly drives LEDs, optocouplers, or small MOSFET gates without external buffers. |
| EMI/RFI filtering | Integrated input filters reject >60 dB of 100-MHz interference - improves reliability in proximity to VFDs and wireless transceivers. |
| Wide temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive subsystems and industrial motor control enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Lower offset drift (±0.2 µV/°C vs ±1.5 µV/°C), but only 36-V max supply and 350-kHz GBW. | Better for ultra-stable DC-coupled instrumentation; unsuitable for 40-V motor drive rails or high-speed PWM monitoring. | Choose OPA2333AIDR when microvolt-level drift dominates design; choose TLV9352IPWR for 40-V operation and 3.5-MHz bandwidth. |
| LM2904BDR | Lower cost, wider temp range (–40°C to 125°C), but only 1.2-MHz GBW, 0.3-V output headroom, and no rail-to-rail inputs. | Acceptable for basic voltage followers and low-speed comparators; lacks MUX-friendliness and noise performance for precision sensing. | Choose LM2904BDR for non-critical biasing or simple amplification; choose TLV9352IPWR when rail-to-rail input/output and low noise are mandatory. |
Compared with OPA2333AIDR and LM2904BDR, TLV9352IPWR uniquely balances 40-V operation, 3.5-MHz bandwidth, rail-to-rail inputs/outputs, and EMI-hardened design - making it the only dual op-amp in this group qualified for direct integration into high-voltage, high-noise industrial power stages without additional protection circuitry.

FAQ
What is the maximum supply voltage rating for TLV9352IPWR?
The TLV9352IPWR has an absolute maximum supply voltage of 42 V (V+ to V–), with recommended operating range from 4.5 V to 40 V. Operation beyond 40 V risks exceeding safe operating area limits and may degrade long-term reliability. TI specifies performance parameters only within the 4.5–40 V range, and thermal derating is required above 30 V at elevated ambient temperatures.
Does TLV9352IPWR support true rail-to-rail input operation?
Yes, TLV9352IPWR supports rail-to-rail differential input voltage range - its inputs operate with common-mode voltages from (V–) – 0.2 V to (V+) – 2 V, and differential input voltage can reach the full supply rail span. This enables direct interfacing with unbuffered analog multiplexers and sensors referenced to either supply rail, a key feature distinguishing it from standard op-amps.
Can TLV9352IPWR be used as a comparator?
Yes, TLV9352IPWR is explicitly designed for open-loop comparator use due to its MUX-friendly inputs and lack of internal phase-reversal circuitry. The datasheet confirms no phase reversal (Figure 6-30) and provides overload recovery times (600 ns). However, it lacks built-in hysteresis or push-pull output - external hysteresis and pull-up/pull-down resistors are required for robust comparator operation.
What is the thermal resistance (RθJA) of TLV9352IPWR in SOIC-8 package?
The TLV9352IPWR in SOIC-8 (D) package has a junction-to-ambient thermal resistance (RθJA) of 138.7°C/W under standard JEDEC JESD51-7 PCB conditions (2-layer board, 1-in² copper pad). This value assumes proper layout with thermal vias and adequate copper pour; actual board-level RθJA will vary based on PCB stack-up and heatsinking. Derating curves in the datasheet require adjustment above 85°C ambient.
Is TLV9352IPWR qualified for automotive applications?
TLV9352IPWR is not AEC-Q100 qualified, though it operates across –40°C to +125°C and meets many functional requirements of automotive subsystems. Its 40-V supply range and EMI hardening suit under-hood motor control, but formal qualification requires additional stress testing and documentation not provided by TI for this part. For AEC-Q100-compliant alternatives, consult TI's automotive-grade op-amp portfolio.
