Product details
Overview
TLV9002IDDFR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power, cost-sensitive systems operating from 1.8 V to 5.5 V supply. It delivers ±0.4 mV input offset voltage, 1 MHz unity-gain bandwidth, 60 µA per channel quiescent current, and stable operation into 500 pF capacitive loads-enabling precision sensor signal conditioning in wearable devices and smoke detectors.
For engineers reviewing the TLV9002IDDFR datasheet, TLV9002IDDFR pinout, TLV9002IDDFR application, or TLV9002IDDFR equivalent, key selection considerations include its resistive open-loop output impedance (simplifying stability with high capacitive loads), integrated RFI/EMI filter, –40°C to 125°C extended temperature range, and compatibility with space-constrained PCB layouts using the 8-pin SOT-23 (DDF) package.
Technical Context
The TLV9002IDDFR implements a scalable CMOS architecture designed specifically for low-voltage, low-cost applications where rail-to-rail swing and capacitive-load drive are critical. Its unity-gain stable design eliminates external compensation, while the resistive open-loop output impedance enables robust performance with up to 500 pF load capacitance without oscillation.
It features internal EMI/RFI filtering and no phase reversal under overdrive conditions-critical for reliable operation in noisy industrial and consumer environments. The device operates across 1.8 V–5.5 V supplies and maintains specified performance over –40°C to +125°C, supporting automotive cabin and industrial control use cases without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual-channel: supports independent amplification paths for differential sensing or multi-signal conditioning on one die. |
| Supply Voltage Range | 1.8 V to 5.5 V: enables direct interface with Li-ion battery-powered systems and 3.3 V/5 V logic domains. |
| Unity-Gain Bandwidth | 1 MHz: sufficient for anti-aliasing, active filtering, and DC-coupled sensor interfaces up to ~100 kHz closed-loop bandwidth. |
| Input Offset Voltage | ±0.4 mV max: ensures <1% error in 100 mV full-scale current-sense applications without trimming. |
| Quiescent Current | 60 µA per channel: allows continuous operation in always-on wearables or battery-backed safety sensors for >1 year on coin cells. |
| Capacitive Load Drive | 500 pF: eliminates need for isolation resistors when driving ADC inputs, display drivers, or long PCB traces. |
| Input/Output Swing | Rail-to-rail: maximizes dynamic range at low supply voltages-e.g., 0–1.8 V output with 1.8 V supply improves SNR in single-supply systems. |
Pinout & Package
TLV9002IDDFR uses an 8-pin SOT-23 (DDF) package measuring 1.60 mm × 2.90 mm with exposed thermal pad connected to V–. This ultra-small outline supports high-density layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Output, Channel 1 | Amplified signal output; rail-to-rail capable; drives capacitive loads up to 500 pF directly. |
| IN1– | Inverting Input, Channel 1 | High-impedance node (5 pA bias current); accepts signals down to V– – 0.5 V. |
| IN1+ | Noninverting Input, Channel 1 | High-impedance node; used for reference-based sensing or unity-gain buffer configuration. |
| V– | Negative Supply / Ground | Reference return path; thermal pad must be soldered to this net for thermal and EMI performance. |
| IN2+ | Noninverting Input, Channel 2 | Independent input for second signal path; identical electrical specs to IN1+. |
| IN2– | Inverting Input, Channel 2 | Independent input for second signal path; supports differential pair or separate sensor channels. |
| OUT2 | Output, Channel 2 | Second rail-to-rail output; electrically isolated from OUT1; shares same supply rails. |
| V+ | Positive Supply | Accepts 1.8 V–5.5 V; internal regulation ensures consistent biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of supply range in single-supply systems-e.g., 0–3.3 V output with 3.3 V supply improves resolution in 12-bit ADC interfaces. |
| Resistive open-loop output impedance | Eliminates peaking and instability with capacitive loads >100 pF, removing need for series damping resistors in sensor-to-ADC paths. |
| Integrated RFI/EMI filter | Rejects common-mode noise from switching power supplies and RF sources without external RC filters-reducing BOM count and board area. |
| Extended temperature range | –40°C to +125°C operation verified per JEDEC JESD22-A108; suitable for under-hood automotive modules and HVAC control units. |
| Low input bias current | 5 pA maximum enables high-impedance source interfacing (e.g., pH electrodes, piezoresistive sensors) without significant voltage drop or drift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher 100 µA/ch quiescent current; 1.0 V/µs slew rate; no integrated EMI filter; 0°C to 70°C temp range. | Limited to commercial-temperature consumer products; less suitable for battery-critical or harsh-environment designs. | Choose LMV358IDR only if legacy qualification or cost sensitivity outweighs power/performance requirements. |
| TLV2462CDR | Higher 550 µA/ch quiescent current; 6.4 V/µs slew rate; rail-to-rail output only; 2.7 V–6 V supply range. | Better for higher-speed signal chains but incompatible with sub-2.7 V battery operation and increases power budget by 9×. | Select TLV2462CDR when bandwidth >1 MHz and drive strength >50 mA are required-otherwise TLV9002IDDFR offers superior efficiency. |
Compared with LMV358IDR and TLV2462CDR, TLV9002IDDFR provides the lowest power consumption in its class while maintaining rail-to-rail I/O, EMI resilience, and extended temperature capability-making it optimal for next-generation portable and safety-critical systems where supply headroom and reliability are constrained.

FAQ
What is the maximum capacitive load the TLV9002IDDFR can drive without instability?
The TLV9002IDDFR is characterized to drive up to 500 pF capacitive load while maintaining unity-gain stability. This specification is validated per TI's test methodology in the datasheet and enables direct connection to ADC inputs, display drivers, or long PCB traces without external isolation resistors or compensation networks. The resistive open-loop output impedance is the key enabler of this performance.
Does the TLV9002IDDFR support single-supply operation?
Yes, the TLV9002IDDFR supports true single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input and output stages allow input signals to swing from V– (typically ground) to V+, and output to reach within millivolts of both rails. This makes TLV9002IDDFR ideal for battery-powered systems where negative supply rails are impractical.
What is the input offset voltage specification for TLV9002IDDFR over temperature?
The TLV9002IDDFR has a maximum input offset voltage of ±0.4 mV at room temperature (25°C), with guaranteed drift of ≤2 µV/°C over –40°C to +125°C. This low drift ensures minimal calibration burden in precision applications like current sensing or temperature transducer amplification across wide ambient ranges.
Is the TLV9002IDDFR pin-compatible with other dual op amps in the TLV900x family?
No-TLV9002IDDFR (SOT-23-8, DDF) is not pin-compatible with TLV9002 variants in SOIC-8, VSSOP-8, or WSON-8 packages due to differing pin assignments. For example, the SOIC-8 variant places V– on pin 4, whereas TLV9002IDDFR places V– on pin 4 but assigns different functions to pins 5–8. Always verify pinout against the specific package drawing in the datasheet.
How does the integrated RFI/EMI filter in TLV9002IDDFR improve system-level noise immunity?
The integrated RFI/EMI filter in TLV9002IDDFR attenuates high-frequency interference (e.g., from switch-mode power supplies or wireless transceivers) before it reaches the input stage, reducing susceptibility to rectification-induced DC offsets. This eliminates the need for external RC filters at each op amp input, saving board space and component cost while improving consistency across production units.
