The MAX1169BEUD+ is an integrated circuit (IC) component that belongs to the MAX1169-1172 family of 8-channel, 12-bit analog-to-digital converters (ADCs). Designed by Maxim Integrated, this IC offers high accuracy, low power consumption, and a compact form factor, making it suitable for a wide range of applications.
One of the key features of the MAX1169BEUD+ is its 8-channel multiplexer, allowing it to perform simultaneous sampling and conversion of analog signals from multiple sources. Each channel has an input range of 0 to VREF, which can be externally set to any voltage between 2.7V and 3.6V. The ADC also provides a differential reference input, which enhances measurement accuracy in the presence of noise.
To achieve high-resolution conversion, the MAX1169BEUD+ utilizes a successive-approximation register (SAR) architecture. This architecture enables it to convert analog signals into 12-bit digital data with a maximum sampling rate of 100ksps (thousand samples per second). Furthermore, the SAR ADC supports both single-ended and differential input modes, offering flexibility in signal measurement.
The IC incorporates an on-chip oscillator that generates the conversion clock signal, eliminating the need for an external clock source. Additionally, it includes a low dropout (LDO) regulator that ensures stable operation even when the input supply voltage fluctuates
