SBAS531B –DECEMBER 2010–REVISED FEBRUARY 2011

16-Bit, Six-Channel, Simultaneous Sampling

ANALOG-TO-DIGITAL CONVERTER

Check for Samples: ADS8555

FEATURES

DESCRIPTION

•

Six SAR ADCs Grouped in Three Pairs

The ADS8555 contains six low-power, 16-bit,

successive approximation register (SAR)-based

analog-to-digital converters (ADCs) with true bipolar

inputs. Each channel contains a sample-and-hold

•

Maximum Data Rate Per Channel with Internal

Clock and Reference:

630kSPS (Parallel) or 450kSPS (Serial)

circuit

that

allows

simultaneous

high-speed

•

Maximum Data Rate Per Channel with External

Clock and Reference:

multi-channel signal acquisition.

The ADS8555 supports data rates of up to 630kSPS

in parallel interface mode or up to 450kSPS if the

serial interface is used. The bus width of the parallel

interface can be set to eight or 16 bits. In serial

mode, up to three output channels can be activated.

800kSPS (Parallel) or 500kSPS (Serial)

•

Pin-Selectable or Programmable Input Voltage

Ranges: Up to ±12V

Excellent AC Performance:

91.5dB SNR, –94dB THD

The ADS8555 is specified over the extended

industrial temperature range of –40°C to +125°C and

is available in an LQFP-64 package.

Programmable and Buffered Internal

Reference: 0.5V to 2.5V and 0.5V to 3.0V

Comprehensive Power-Down Modes:

Deep Power-Down (Standby Mode)

Auto-Nap Power-Down
