%FSR Gain Error
The ADS8472 is an 16-bit, 1-MSPS A/C converter
±0.4-PPM/°C
Gain Error Drift
with an internal 4.096-V reference and a
95dB SNR, -120dB THD, 123dB SFDR
pseudo-bipolar, fully differential input. The device
includes a 16-bit capacitor-based SAR A/D converter
Zero Latency
with inherent sample and hold. The ADS8472 offers
Low Power: 225 mW at 1 MSPS
a full 16-bit interface or an 8-bit bus option using two
Unipolar Differential Input Range: V
ref
to –Vref
read cycles.
Onboard Reference with 6 PPM/°C Drift
The ADS8472 is available in a 48-lead 7x7 QFN
Onboard Reference Buffer
package and is characterized over the industrial
–40°C to 85°C temperature range.
