Linear Technology LTC2355CMSE-14#TRPBF
- Part Number:
- LTC2355CMSE-14#TRPBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3012921-LTC2355CMSE-14#TRPBF
- Description:
- IC ADC 14BIT 3.5MSPS 10-MSOP
- Datasheet:
- LTC2355CMSE-14#TRPBF
Description
The LTC2355-12/LTC2355-14 are 12-bit/14-bit, 3.5Msps serial ADCs with differential inputs. They operate on a single 3.3V supply, consume only 5.5mA, and come in a compact 10-lead MSOP package. A Sleep shutdown mode further reduces power consumption to 13μW. The combination of speed, low power, and small size makes these ADCs suitable for high-speed, portable applications.
The 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The devices convert 0V to 2.5V unipolar inputs differentially. The absolute voltage swing for AN and AIN extends from ground to the supply voltage.
The serial interface sends out the conversion results during the 16 clock cycles following a CONV rising edge for compatibility with standard serial interfaces. If two additional clock cycles for acquisition time are allowed after the data stream in between conversions, the full sampling rate of 3.5Msps can be achieved with a 63MHz clock.
