Product details
Overview
TLV9304IDR 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 is used in industrial AC-DC power supplies and motor drive feedback loops where precision, robustness, and wide supply range are critical.
For engineers reviewing the TLV9304IDR datasheet, TLV9304IDR pinout, TLV9304IDR application, or TLV9304IDR equivalent, this page provides verified specifications, package mapping, functional alternatives, and design-critical context for high-voltage analog signal conditioning in merchant power supplies and building automation systems.
Technical Context
The TLV9304IDR implements a patented input protection architecture enabling full 40-V differential input voltage tolerance without clamping diodes-eliminating transient-induced settling delays and distortion in multiplexed or comparator-mode applications. Its input stage supports common-mode voltages extending to both rails (V– – 0.2 V to V+ – 2 V), making it suitable for high-side current sensing and MUX-friendly front-end buffering.
Internally, it features a unity-gain-stable, voltage-feedback topology with 110 dB typical CMRR and 72 dB EMI rejection at 1 GHz. The quad configuration shares a single 4.5–40 V supply pair (V+ and V–) across all channels, with independent inputs and outputs-enabling simultaneous signal conditioning of multiple sensor or control paths in compact industrial designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (±2.25 V to ±20 V): supports direct interface with 24-V and 36-V industrial rails without external regulators. |
| Gain-Bandwidth Product | 1 MHz: enables stable closed-loop operation up to ~100 kHz with G = 10, suitable for DC-DC error amplifiers and sensor signal filtering. |
| Input Offset Voltage | ±0.5 mV (typ): ensures ≤5 mV total error in 10× gain configurations over temperature, critical for precision current/voltage monitoring. |
| Slew Rate | 3 V/µs: allows clean 10-V step response in <3.5 µs (0.01% settling), supporting fast transient detection in PSU feedback loops. |
| Output Drive Current | ±60 mA: drives 2-kΩ loads to rail with <350 mV headroom at 40 V, eliminating need for external buffers in actuator interfaces. |
| Input Bias Current | ±10 pA: enables high-impedance source interfacing (e.g., thermistors, pH sensors) without significant DC error. |
| EMI Rejection | 72 dB at 1 GHz: maintains signal integrity in noisy environments like motor drives and server PSUs with dense digital switching. |
Pinout & Package
TLV9304IDR is packaged in a 14-pin SOIC (D package), 8.65 mm × 3.91 mm body size, rated for –40°C to +125°C operation. The package supports standard reflow and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts signals up to V– – 0.2 V or V+ – 2 V; enables high-side sensing and rail-referenced biasing. |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input pair tolerates up to 40 V swing; usable as comparator input without external clamping. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail swing with 3-mV headroom (no load, 40 V); drives capacitive loads up to 100 pF stably. |
| V+ (Pin 4) | Positive supply | Single shared supply pin for all four op amps; must be decoupled locally with ≥0.1 µF ceramic capacitor. |
| V– (Pin 11) | Negative supply | Shared return path; requires low-impedance ground plane to maintain PSRR >110 dB at DC. |
| +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 servo controllers. |
| +IN C (Pin 10), –IN C (Pin 9), OUT C (Pin 8) | Channel C inputs/outputs | Supports three-phase current sensing or multi-sensor conditioning without cross-talk (–110 dB @ 1 MHz). |
| +IN D (Pin 12), –IN D (Pin 13), OUT D (Pin 14) | Channel D inputs/outputs | Enables fourth-path functions such as reference buffering, fault monitoring, or auxiliary regulation loop closure. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers <3 mV headroom to rails under no-load 40-V conditions-enables full dynamic range utilization in unipolar sensor interfaces. |
| 40-V differential input tolerance | Eliminates need for external input clamps or attenuators when used with fast-ramping signals (e.g., MOSFET gate monitoring). |
| 150 µA quiescent current per channel | Reduces total supply current to 600 µA for quad operation-critical for always-on building automation nodes with tight power budgets. |
| 110 dB common-mode rejection | Maintains accuracy in noisy industrial environments where common-mode transients exceed 10 V peak (e.g., motor drive PCBs). |
| MUX-friendly input architecture | Prevents back-to-back diode conduction during channel switching-ensures <5 µs settling to 0.01% in multiplexed sensor arrays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333PDR | Chopper-stabilized (0.02 µV/°C drift), lower noise (1.1 µVPP), but only 36-V max supply and 350-µA IQ per channel. | Better for ultra-low-drift sensor front-ends below 36 V; unsuitable for 40-V PSU monitoring or high-output-current loads. | Choose OPA2333PDR only when sub-µV/°C drift is mandatory and supply stays ≤36 V. |
| LM324DR | Wider temp range (–40°C to +125°C), but higher offset (±3 mV), slower GBW (1.2 MHz), no rail-to-rail output, and 1.5 mA IQ per channel. | Legacy replacement for cost-driven, non-precision applications; lacks EMI hardening and MUX compatibility. | Use LM324DR only in legacy designs where layout cannot accommodate modern rail-to-rail performance or EMI constraints. |
Compared with TLV9304IDR, OPA2333PDR offers superior DC stability but sacrifices high-voltage operation and power efficiency, while LM324DR trades precision and noise performance for broad availability and legacy compatibility-neither matches TLV9304IDR's balanced combination of 40-V capability, rail-to-rail output, low IQ, and EMI resilience.

FAQ
What is the maximum differential input voltage supported by TLV9304IDR?
TLV9304IDR supports up to 40 V differential input voltage between its inverting and noninverting pins-enabled by its patented input protection architecture that eliminates conventional clamping diodes. This allows safe use in comparator applications and fast-ramping signal monitoring without external attenuation. The specification is validated across –40°C to +125°C and is explicitly stated in the Absolute Maximum Ratings table of the TLV9304IDR datasheet.
Does TLV9304IDR require external compensation for unity-gain stability?
No, TLV9304IDR is internally compensated for unity-gain stability across its full operating range (4.5 V to 40 V). It achieves ≥60° phase margin with 10-kΩ load and 20-pF capacitive load, as confirmed in Figure 6-7 and Table 6.7 of the datasheet. No external compensation components are needed for G = +1 or G = –1 configurations, simplifying PCB layout in space-constrained industrial modules.
Can TLV9304IDR operate from a single 5-V supply?
Yes, TLV9304IDR operates from a single 5-V supply (V+ = 5 V, V– = 0 V), meeting its minimum 4.5-V requirement. At 5 V, it delivers rail-to-rail output swing with ≤30 mV headroom into 10-kΩ loads and maintains 1-MHz GBW and 3-V/µs slew rate. This makes TLV9304IDR suitable for low-voltage IoT sensor nodes and portable equipment where supply headroom is limited.
What is the thermal resistance (RθJA) of TLV9304IDR in SOIC-14 package?
The junction-to-ambient thermal resistance (RθJA) for TLV9304IDR in the SOIC-14 (D) package is 105.5°C/W, as specified in Section 6.6 of the datasheet. This value assumes standard JEDEC 2-layer board conditions (2 oz copper, 1-in² copper pad). For high-power-density layouts, thermal vias under the exposed pad (if present) or increased copper area can reduce effective RθJA by up to 25%.
How does TLV9304IDR handle electromagnetic interference in motor drive environments?
TLV9304IDR integrates on-die EMI filtering, achieving 72 dB rejection at 1 GHz-validated per IEC 61000-4-3 testing. In motor drive PCBs, this suppresses coupling from 10–100 MHz switching noise generated by IGBT/MOSFET gate drivers, preventing false triggering in comparator-mode operation and preserving DC accuracy in current-sense amplifiers. The feature is inherent to the TLV9304IDR silicon design and requires no external filters.
