概述

Description

AD5246BKSZ100-RL7 is an Analog Devices digital potentiometer. It provides a programmable wiper a.k.a. adjustable resistance in a signal path, controlled over I2C.
Key points
- Resolution: 6-bit wiper (64 positions)
- End-to-end resistance: 100 kΩ (the “100” in the part number)
- Interface: I2C-friendly digital control
- Package: SZ-series small-outline, RoHS-compliant (RL7 suffix indicates lead-free)
- Use cases: adjustable gain/attenuation, calibration, sensor front-ends, volume control, or any application needing precise, MCU-controlled resistance
Notes
- Exact electrical specs (wiper resistance, voltage range, current drive, addressing, timing) vary by device variant; see the AD5246 datasheet for detailed limits and programming sequences.
- Typical supply range is in the common 1.8–5.5 V region for these parts.
If you need precise timing, current consumption, or nonvolatile memory behavior, refer to the datasheet for the specific AD5246B variant.

Features

Key features of AD5246BKSZ100-RL7 (concise):
- 6-channel I2C-controlled digital potentiometer array
- End-to-end resistance: 100 kΩ per channel
- Independent programmable wipers with nonvolatile memory (retains settings)
- I2C serial interface (addressable; supports standard/fast-mode)
- Low-power operation; suitable for battery-powered designs
- RoHS-compliant, lead-free package (BKSZ100-RL7)
Note: Refer to the datasheet for exact supply voltage range, current consumption, timing, and detailed electrical characteristics.

Package

8-lead MSOP package (MSOP-8), RoHS compliant; comes in tape-and-reel packaging.

Pinout

- Pin count: 16 pins (SZ package)
- Function: Dual 100 kΩ I2C-controlled digital potentiometer. Two independent pots (A1–B1–W1 and A2–B2–W2) with SDA/SCL interface, plus VDD/GND and address/config pins for I2C communication. Used for programmable attenuation/gain in analog paths.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded-processing integrated circuits (ICs).

Application

AD5246BKSZ100-RL7 is a 6-channel I2C digital potentiometer (100 kΩ end-to-end). Applications include:
- Remote gain/attenuation control in op-amps and instrumentation amplifiers
- Sensor calibration and ADC/DAC offset and gain trimming
- Programmable attenuators/volume control in audio paths
- Bias/reference networks and programmable filter tuning
- Replacement for multiple mechanical pots in test, instrumentation, and consumer electronics
