Description
LT1964EDD#TRPBF is an Analog Devices/Linear Technology LED-driver IC in an 8-pin Pb-free package (TRPBF TamTape). It provides a constant-current source to drive LED strings, with the current set by an external sense resistor and feedback network. Key features typically include dimming control (analog or PWM), protection against overcurrent and thermal shutdown, and operation over a wide input range suitable for battery or rail power. The EDD suffix indicates the specific package variant, while #TRPBF denotes Tape-and-Reel Pb-free packaging. This part is used for LED backlighting, indicators, and similar lighting applications. For exact electrical specs, pinout, and application circuits, refer to the LT1964 datasheet.
Pinout
- Pin count: 8 pins (8-lead package)
- Function: Dual operational amplifier (two op-amps in one package; Pb-free, tape-and-reel).
- Function: Dual operational amplifier (two op-amps in one package; Pb-free, tape-and-reel).
Manufacturer
Analog Devices, Inc. (ADI) — the company that now owns the Linear Technology product line (LT1964). ADI is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.
Application
LT1964EDD#TRPBF is a precision, low-noise op-amp. Common application areas include:
- Sensor signal conditioning (bridge sensors, RTDs, thermocouples)
- Transimpedance and photodiode front-ends
- ADC input buffers and active filters
- Servo/control-loop amplifiers in automation and instrumentation
- Medical and industrial instrumentation requiring low offset and drift
- Audio preamplification where low noise is critical
