LTC2356-12/LTC2356-14

Serial 12-Bit/14-Bit, 3.5Msps

Sampling ADCs with Shutdown

FEATURES

DESCRIPTION

TheLTC^®2356-12/LTC2356-14are12-bit/14-bit, 3.5Msps

3.5Msps Conversion Rate

74.1dB SINAD at 14-Bits, 71.1dB SINAD at 12-Bits

Low Power Dissipation: 18mW

serial ADCs with differential inputs. The devices draw

only 5.5mA from a single 3.3V supply and come in a

tiny 10-lead MSOP package. A Sleep shutdown feature

further reduces power consumption to 13µW. The com-

bination of speed, low power and tiny package makes the

LTC2356-12/LTC2356-14suitableforhighspeed,portable

applications.

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

80dB Common Mode Rejection

The80dBcommonmoderejectionallowsuserstoeliminate

ground loops and common mode noise by measuring

signals differentially from the source.

1.25V Bipolar Input Range

extends from ground to the supply voltage.

Data Acquisition Systems

Theserialinterfacesendsouttheconversionresultsduring

the 16 clock cycles following a CONV rising edge for com-

patibility 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.
