SBAS098A – JANUARY 1998 – REVISED SEPTEMBER 2003

12-Bit High-Speed, Low-Power Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

ꢀ 500kHz THROUGHPUT RATE

ꢀ 2.5V INTERNAL REFERENCE

ꢀ LOW POWER: 11mW

The ADS7834 is a 12-bit sampling analog-to-digital converter

(A/D) complete with sample/hold, internal 2.5V reference,

and synchronous serial interface. Typical power dissipation

is 11mW at a 500kHz throughput rate. The device can be

placed into a power-down mode that reduces dissipation to

just 2.5mW. The input range is zero to the reference voltage,

and the internal reference can be overdriven by an external

voltage.

ꢀ SINGLE-SUPPLY +5V OPERATION

ꢀ DIFFERENTIAL INPUT

ꢀ SERIAL INTERFACE

ꢀ 12-BITS NO MISSING CODES

ꢀ MINI-DIP-8 AND MSOP-8

ꢀ 0V TO V_REFINPUT RANGE

Low power, small size, and high speed make the ADS7834

ideal for battery-operated systems such as wireless

communication devices, portable multi-channel data loggers,

and spectrum analyzers. The serial interface also provides

low-cost isolation for remote data acquisition. The ADS7834

is available in a plastic mini-DIP-8 or an MSOP-8 package

and is ensured over the –40°C to +85°C temperature range.
