DIN DOUT SCLK POLARITY

The AD7853/AD7853L are high speed, low power, 12-bit

ADCs that operate from a single 3 V or 5 V power supply, the

AD7853 being optimized for speed and the AD7853L for low

power. The ADC powers up with a set of default conditions at

which time it can be operated as a read-only ADC. The ADC

contains self-calibration and system-calibration options to en-

sure accurate operation over time and temperature and have a

number of power-down options for low power applications.

The part powers up with a set of default conditions and can

operate as a read only ADC.

PRODUCT HIGHLIGHTS

1. Specified for 3 V and 5 V supplies.

2. Automatic calibration on power-up.

3. Flexible power management options including automatic

power-down after conversion.

4. Operates with reference voltages from 1.2 V to V_DD

The AD7853 is capable of 200 kHz throughput rate while the

AD7853L is capable of 100 kHz throughput rate. The input

track-and-hold acquires a signal in 500 ns and features a pseudo-

differential sampling scheme. The AD7853/AD7853L voltage

range is 0 to V_REFwith both straight binary and twos comple-

ment output coding. Input signal range is to the supply, and the

part is capable of converting full power signals to 100 kHz.

5. Analog input ranges from 0 V to V_DD

6. Self- and system calibration.

7. Versatile serial I/O port (SPI/QSPI/8051/µP).

8. Lower power version AD7853L.

CMOS construction ensures low power dissipation of typically

4.5 mW for normal operation and 1.15 mW in power-down

mode, with a throughput rate of 10 kSPS (V_DD= 3 V). The part

is available in 24-lead, 0.3 inch wide dual-in-line package

(DIP), 24-lead small outline (SOIC) and 24-lead small shrink

outline (SSOP) packages.
