Maxim Integrated MAX1271ACAI
- Part Number:
- MAX1271ACAI
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3007299-MAX1271ACAI
- Description:
- IC ADC 12BIT 8CH 28-SSOP
- Datasheet:
- MAX1271ACAI
Description
The MAX1270/MAX1271 are multirange, 12-bit data acquisition systems (DAS) that require only a single 5V supply for operation. They accept signals at their analog inputs that can span above the power-supply rail and below ground. These systems provide eight analog input channels that are independently software programmable for a variety of ranges:
MAX1270: ±10V, ± 5V, 0 to 10V, 0 to 5V
MAX1271: ±VREF, ±VREF/2, 0 to VREF. 0 to VREF/2
This range switching increases the effective dynamic range to 14 bits and provides the flexibility to interface 4-20mA, ±12V, and 15V powered sensors directly to a single 5V system.
In addition, these converters are fault protected to ±16.5V; a fault condition on any channel will not affect the conversion result of the selected channel. Other features include a 5MHz bandwidth track/hold, software-selectable internal/external clock, 110ksps throughput rate, and internal 4.096V or external reference operation.
The MAX1270/MAX1271 serial interface directly connects to SPI/QSPI and MICROWIRE devices without external logic.
A hardware shutdown input (SHDN) and two software-programmable power-down modes, standby (STBYPD) or full power-down (FULLPD), are provided for low-current shutdown between conversions. In standby mode, the reference buffer remains active, eliminating startup delays.
The MAX1270/MAX1271 are available in 24-pin narrow PDIP or space-saving 28-pin SSOP packages.
