Linear Technology LTC2312HTS8-12#TRMPBF

Description
The LTC2312-12 is a 12-bit, 500ksps serial sampling ADC that operates on a single 3V or 5V supply. It features an integrated low-drift reference and reference buffer, providing a cost-effective and space-saving solution. The LTC2312-12 offers outstanding AC performance with a 72.7dB SINAD and -84dB THD while sampling at 500ksps. Its high sample rate-to-power ratio makes it ideal for compact, low-power, high-speed systems. The device automatically enters nap mode after conversions, reducing supply current at lower sampling rates.
