ADCs/DACs - Special Purpose datasheet and documents for MAX1271BEAI+T
ADCs/DACs - Special Purpose Overview
The MAX1271BEAI+T is a multirange, 8-channel, serial 12-bit data acquisition system (DAS) from Analog Devices/Maxim Integrated. It operates on a single +5V supply while accepting analog input signals spanning above the power-supply rail and below ground. The device features an 110ksps throughput rate, ±16.5V overvoltage-tolerant inputs, and software-selectable input ranges including ±VREF, ±VREF/2, 0 to VREF, and 0 to VREF/2. It utilizes a 3-wire SPI/QSPI/MICROWIRE-compatible interface and includes internal or external reference options with two power-down modes for low-current operation.

ADCs/DACs - Special Purpose Procurement Notes
Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C compared to the commercial 'C' grade. Confirm package type is 28-pin SSOP. Check current availability status as distribution may vary by region.
ADCs/DACs - Special Purpose Selection Notes
Select this model for applications requiring high channel count and wide input voltage flexibility on a single 5V supply. Ensure the microcontroller supports the required serial interface timing. Consider the -40°C to +85°C operating range if environmental conditions exceed standard industrial limits.
ADCs/DACs - Special Purpose Part Context
This component belongs to the MAX1270/MAX1271 family of multirange ADCs. The MAX1271 variant specifically offers programmable ranges based on the reference voltage (±VREF, etc.), whereas the MAX1270 uses fixed voltage ranges. The 'B' grade specifies ±1 LSB INL accuracy.
ADCs/DACs - Special Purpose Replacement Considerations
MAX1271BCAI+ (Commercial grade, same electrical specs but 0°C to +70°C range). MAX1271AEAI+ (A grade, lower speed 100ksps, tighter linearity ±0.5 LSB INL).
