LTC1403/LTC1403A

Serial 12-Bit/14-Bit, 2.8Msps

Sampling ADCs with Shutdown

FEATURES

DESCRIPTIO

The LTC^®1403/LTC1403A are 12-bit/14-bit, 2.8Msps se-

rial ADCs with differential inputs. The devices draw only

4.7mA from a single 3V supply and come in a tiny 10-lead

MS package. A Sleep shutdown feature lowers power

consumption to 10µW. The combination of speed, low

power and tiny package makes the LTC1403/LTC1403A

suitable for high speed, portable applications.

2.8Msps Conversion Rate

■

Low Power Dissipation: 14mW

■

3V Single Supply Operation

■

2.5V Internal Bandgap Reference can be Overdriven

■

3-Wire Serial Interface

■

Sleep (10µW) Shutdown Mode

■

Nap (3mW) Shutdown Mode

■

80dB Common Mode Rejection

The 80dB common mode rejection allows users to elimi-

nategroundloopsandcommonmodenoisebymeasuring

signals differentially from the source.

■

0V to 2.5V Unipolar Input Range

■

Tiny 10-Lead MS Package

The devices convert 0V to 2.5V unipolar inputs differen-

tially. The absolute voltage swing for +A_INand –A_IN

extends from ground to the supply voltage.

APPLICATIO S

■

Communications

Data Acquisition Systems

■

The serial interface sends out the conversion results

during the 16 clock cycles following CONV↑ for compat-

ibility 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

2.8Msps can be achieved with a 50.4MHz clock.
