Product details
Overview
TLE2662IDWR from Texas Instruments is a dual µPower JFET-input operational amplifier integrated with a switched-capacitor voltage converter in a single 16-pin SOIC (DW) package. It delivers rail-to-rail input operation, ±25 mA output sink capability, and generates up to –5 V at 100 mA from a single 3.5–15 V supply-enabling true bipolar signal conditioning in single-supply sensor front-ends and portable instrumentation.
For engineers reviewing the TLE2662IDWR datasheet, TLE2662IDWR pinout, TLE2662IDWR application, or TLE2662IDWR equivalent, this device offers verified JFET-input performance (1 pA bias current, 10¹² Ω input resistance), on-chip negative rail generation, shutdown control via FB/SD, and industrial temperature support (–40°C to 85°C) for low-power analog signal chains requiring precision and supply flexibility.
Technical Context
The TLE2662IDWR integrates two independent JFET-input op-amps with a dedicated switched-capacitor voltage inverter block. The SC section operates at a nominal 25 kHz oscillator frequency, supports external synchronization or capacitor-based frequency tuning, and provides a regulated –5 V output (±50 mV line/load regulation) with an internal 2.5-V reference accessible at SCREF.
Each amplifier features unity-gain bandwidth of 1.8 MHz (±5 V), slew rate of 2.2 V/µs, and rail-to-rail input range extending beyond ground-enabled by the SC-generated VCC– rail. Shutdown mode reduces total supply current to ≤265 µA while preserving SCREF and oscillator functionality for fast wake-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 3.5 V to 15 V single supply; enables direct battery or unregulated DC input without external regulators |
| Input Bias Current | 1 pA typical at 25°C; preserves high-impedance sensor node integrity and minimizes offset drift |
| Output Drive | Sinks ≥25 mA to 0 V; drives 100-Ω loads to ±2.5 V from 5-V rail-supports active filtering and direct interface to ADC drivers |
| SCOUT Output | –4.7 V to –5.2 V at 500 Ω load; supplies up to 100 mA negative rail for op-amp biasing and external circuitry |
| Shutdown Current | ≤150 µA (SC block only); ≤265 µA total system current in shutdown-extends battery life in intermittent-use systems |
| Operating Temp | –40°C to +85°C industrial range; qualified for embedded industrial sensors and portable test equipment |
| Input Resistance | 10¹² Ω; eliminates loading error on high-Z sources like piezoelectric transducers and pH electrodes |

| SCREF | 2.5-V reference output | Stable, buffered 2.5 V reference; usable for ADC references, comparator thresholds, or SC regulator feedback |
| OSC | Oscillator control | Accepts external clock (≤35 kHz) or external capacitor to adjust SC frequency-reduces EMI in noise-sensitive designs |
| SCIN, CAP+, CAP– | SC network terminals | Interface to external timing capacitors; configures SC as inverter/regulator-no inductors required |
| FB/SD | Feedback/shutdown control | Logic-low disables SC block (≤150 µA quiescent); logic-high enables-provides precise power-state control |
| GND | Analog ground reference | Common return for SC block and amplifier sections; requires low-impedance PCB connection to minimize noise |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Extends from VCC– to VCC+ (e.g., –5 V to +5 V), enabling full-scale signal capture from single-supply sensors |
| Integrated negative rail generator | Eliminates need for external charge pumps or inductor-based DC/DC converters-reduces BOM count and board area |
| Ultra-low input bias current | 1 pA typical ensures minimal error in high-impedance transducer interfaces (e.g., photodiode amps, pH probes) |
| Shutdown with fast wake-up | FB/SD pin disables SC block only; op-amps remain powered-allows rapid resumption of analog signal path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp with integrated power conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX44267ASA+ | Dual rail-to-rail op-amp with integrated LDO (not switched-capacitor); no negative rail generation; 1.8 V min supply. | Lacks SCOUT functionality-requires external negative supply for true bipolar operation. | Select when only positive auxiliary rail needed and ultra-low supply voltage (<3.5 V) is critical. |
| LM7322MMX/NOPB | Dual JFET-input op-amp only; no integrated voltage converter; higher supply current (1.3 mA vs 0.62 mA). | Requires external charge pump (e.g., ICL7660) for negative rail-increases layout complexity and noise. | Select when higher speed (20 MHz GBW) and output drive (100 mA) outweigh integration benefits. |
Compared with MAX44267ASA+ and LM7322MMX/NOPB, the TLE2662IDWR uniquely combines JFET-input precision, on-chip negative rail generation, and <620 µA quiescent current-making it the only solution that eliminates external DC/DC components while supporting true rail-to-rail input and output in single-supply systems.

FAQ
What is the maximum output current capability of the TLE2662IDWR's SCOUT pin?
The TLE2662IDWR's SCOUT pin delivers up to 100 mA of continuous output current into a 500-Ω load at –5 V, with voltage loss under load specified at ≤1.6 V (at 100 mA, SCIN = 7 V). This enables direct powering of op-amp stages and small external analog circuits without additional regulators.
Does the TLE2662IDWR support rail-to-rail input operation with a single 5-V supply?
Yes-the TLE2662IDWR achieves true rail-to-rail input operation from a single 5-V supply because its integrated switched-capacitor block generates a VCC– rail (typically –5 V), allowing the common-mode input range to extend from –5 V to +5 V. This is confirmed in the datasheet's VICR specification (–1.6 V to +4 V at ±5 V supplies, extended to full rails when SC is active).
How does the FB/SD pin function in the TLE2662IDWR?
The FB/SD pin on the TLE2662IDWR serves dual roles: when pulled low (≤0.8 V), it disables the switched-capacitor block, reducing its supply current to ≤150 µA; when high (≥2.0 V), it enables normal SC operation. The op-amp section remains fully functional during shutdown-allowing selective power gating of the SC rail while retaining analog signal path readiness.
What is the typical input offset voltage of the TLE2662IDWR over temperature?
The TLE2662IDWR has a typical input offset voltage of 1 mV at 25°C and a maximum of 6.3 mV across the full industrial temperature range (–40°C to +85°C), with a temperature coefficient of 6 µV/°C. This stability supports precision DC-coupled applications such as strain gauge amplification and thermocouple conditioning.
Can the TLE2662IDWR operate from a 3.5-V supply while delivering full SCOUT output?
Yes-the TLE2662IDWR is rated for SCIN down to 3.5 V, and at this minimum supply, SCOUT delivers –3.75 V (typical) at 500 Ω load. While output voltage magnitude decreases linearly with input voltage, the SC block remains functional and regulated, enabling compact low-voltage systems like coin-cell-powered sensors.
