MAX187CCWE 12-bit serial analog-to-digital converter 1 Input 1 SAR 16-SOIC
The MAX187CCWE is a high-precision, low-power, 12-bit serial analog-to-digital converter (ADC) from Analog Devices. This device integrates a sample-and-hold, voltage reference, and serial interface into a compact package, providing a complete data acquisition solution. Operating from a single +5V power supply, it features a fast 8.5 µs conversion time and a three-wire SPI/QSPI™/MICROWIRE™ compatible interface. Designed for high-accuracy signal digitization in space-constrained and power-sensitive applications, it is commonly used for monitoring sensors, measuring battery voltage, and capturing analog signals in portable instrumentation and industrial systems.
This 12-bit ADC uses a successive-approximation register (SAR) architecture to achieve a maximum sampling rate of 75k samples per second. It offers a low power consumption of 1.5 mA during operation and features a software-selectable power-down mode that reduces current to 2 µA. The device includes an internal 4.096V precision bandgap reference, eliminating the need for an external reference. Key specifications include ±0.5 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL), ensuring high accuracy. It accepts a 0V to +5V analog input range. Housed in a 16-pin wide SOIC package, it is specified for the commercial temperature range (0°C to +70°C).
