Texas Instruments ADS8555
The ADS8555 device 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 circuit that allows simultaneous high-speed multichannel signal acquisition. The ADS8555 device supports data rates of up to 630 kSPS in parallel interface mode or up to 450 kSPS if the serial interface is used.| Part No. | ADS8555 |
