概要
Description
Key features:
- Low power consumption (250 µA active, 1 µA standby).
- Small SOT-23-5 package, ideal for space-constrained designs.
- Internal reference voltage, eliminating the need for an external reference.
Applications include sensor interfacing, battery monitoring, and portable devices. Its I²C compatibility simplifies integration with microcontrollers.
The A6T variant has a fixed I²C address (0x4D), ensuring easy addressing in multi-device setups.
For more details, refer to the datasheet on Microchip’s website.
Equivalent
- ADS1015 (Texas Instruments)
- LTC2309 (Analog Devices)
- MAX11613 (Maxim Integrated)
- PCA9540 (NXP, for I2C multiplexing if needed)
These offer similar 12-bit resolution and I2C interfaces. Check datasheets for exact pin compatibility and features.
Pinout
1. VDD – Power supply (2.7V to 5.5V).
2. VSS – Ground.
3. SCL – I²C clock input.
4. SDA – I²C bidirectional data line.
5. VIN – Analog input (0V to VDD).
It operates as a single-channel ADC with an I²C interface (up to 400 kHz). The device provides 12-bit resolution with a single-ended input and includes an internal voltage reference.
Key Features:
- Small form factor (SOT-23-5).
- Low power consumption (typical 250 µA at 5V).
- I²C address options (factory-set, e.g., 0x4D for A6 variant).
Ideal for battery-powered, space-constrained applications.
Application
- Portable Electronics: Battery-powered devices like sensors and wearables.
- Industrial Systems: Process monitoring, control systems, and data logging.
- Consumer Electronics: Smart home devices, audio equipment, and touch interfaces.
- Automotive: Sensor interfaces for non-critical systems.
- Medical Devices: Compact health monitoring tools.
Its I²C interface, low power consumption (~250 µA active), and small SOT-23 package make it ideal for space-constrained designs.
