LTC2355-12/LTC2355-14

Serial 12-Bit/14-Bit, 3.5Msps

Sampling ADCs with Shutdown

FEATURES

DESCRIPTIO

TheLTC^®2355-12/LTC2355-14are12-bit/14-bit,3.5Msps

3.5Msps Conversion Rate

■

serial ADCs with differential inputs. The devices draw only

5.5mAfromasingle3.3Vsupplyandcomeinatiny10-lead

MSOP package. A Sleep shutdown feature further reduces

power consumption to 13µW. The combination of speed,

low power and tiny package makes the LTC2355-12/

LTC2355-14 suitable for high speed, portable applications.

74.2dB SINAD at 14-Bits, 71.1dB SINAD at 12-Bits

Low Power Dissipation: 18mW

3.3V Single Supply Operation

■

2.5V Internal Bandgap Reference can be Overdriven

■

3-Wire SPI-Compatible Serial Interface

■

Sleep (13µW) Shutdown Mode

■

Nap (4mW) Shutdown Mode

The 80dB common mode rejection allows users to elimi-

nategroundloopsandcommonmodenoisebymeasuring

signals differentially from the source.

APPLICATIO S

The absolute voltage swing for A and A extends from

ground to the supply voltage.

Communications

■

Theserialinterfacesendsouttheconversionresultsduring

the 16 clock cycles following a CONV rising edge for

compatibility with standard serial interfaces. If two addi-

tional 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.
