MAXIM INTEGRATED / ANALOG DEVICES MAX1228BEEP Analog-to-Digital Converter
The MAX1228BEEP+ is a 12-bit, 300KSPS analog-to-digital converter (ADC) featuring a built-in FIFO, temperature sensor, and internal voltage reference. Packaged in a 20-pin QSOP, this low-power ADC supports serial output and multichannel operation, ideal for temperature control, process monitoring, and sensing applications. It uses a fully differential successive approximation register (SAR) conversion method and includes an on-chip temperature/voltage channel. The device supports both single-ended and differential input modes, with configurable signal ranges. It offers advanced features including scan mode, internal clock operation, averaging, and auto-shutdown to optimize power and performance. The supply voltage ranges from 4.75V to 5.25V, with an operating temperature range from -40°C to 85°C. It includes 12 input channels, with an internal temperature sensor accurate to ±0.7°C. The ADC provides high accuracy with ±1 LSB INL and DNL, and has no missing codes. Typical current consumption is 2.3mA at 300KSPS with a +5V supply. Internal reference voltage is 4.096V or an external differential reference. Communication is via a 10MHz 3-wire SPI/QSPI/MICROWIRE-compatible interface.
