Description

The MAX1246BEEE is a precision, low-power, 12-bit analog-to-digital converter (ADC) from Maxim Integrated. It operates with a single 2.7V to 5.25V power supply and is designed for applications requiring high accuracy and low power consumption. The MAX1246BEEE features a successive approximation register (SAR) architecture, which ensures fast conversion times and precise results.
Key features include a low power consumption of 135µA at 100ksps, a built-in 2.5V reference, and a serial interface compatible with SPI, QSPI, and MICROWIRE. It also includes an analog input range of 0V to VREF, making it suitable for a variety of sensor and data acquisition applications. The device is housed in a compact form factor, making it ideal for space-constrained applications.
Typical applications for the MAX1246BEEE include portable data logging, battery-powered devices, and any system requiring efficient, high-resolution analog-to-digital conversion. Its efficient design and versatile functionality make it a reliable choice for engineers looking to integrate precision ADC capabilities into their projects.

Features

The MAX1246BEEE is a 12-bit analog-to-digital converter (ADC) from Maxim Integrated. It features a low power consumption which makes it suitable for battery-operated devices. Operating with a single 2.7V to 3.6V supply voltage, it ensures efficient performance in low-voltage applications. This ADC has a serial interface, which simplifies connections to microcontrollers and other digital systems.
The MAX1246BEEE provides a sampling rate of up to 100ksps, which is adequate for many medium-speed data acquisition applications. It includes an internal track-and-hold circuit and has a low input capacitance, which simplifies the design requirements for external analog signal conditioning circuitry.
Additionally, the device incorporates an internal reference, but it also allows the use of an external reference to increase flexibility in precision-critical applications. Its small form factor, typically available in an 8-pin SO package, is ideal for compact electronic designs.
Overall, the MAX1246BEEE is designed for applications requiring reliable 12-bit resolution, low power consumption, and a compact, easy-to-integrate serial interface.
