LTC2376-20: 20-Bit, 250Ksps ADC LTC2377-20: 20-Bit, 500Ksps ADC LTC2378-20: 20-Bit, 1Msps ADC.
The following parts (DUT) are pin-compatible, 20-bit A/D converters with serial I/O, and an internal reference: LTC2376-20: 20-Bit, 250Ksps ADC LTC2377-20: 20-Bit, 500Ksps ADC LTC2378-20: 20-Bit, 1Msps ADC The DUTs typically draw only 8.4 mA from a single 2.5V supply. The automatic nap and sleep modes benefit power sensitive applications. The DUTs DC performance is outstanding with a +/-0.5 ppm INL specification and no missing codes over temperature. The signal-to-noise ratio (SNR) for the LTC2378 is typically 104 dB, with the internal reference. Example Code: Read ADC input. LTC2378_read(LTC2378_CS, &adc_code); // Throws out last reading LTC2378_read(LTC2378_CS, &adc_code); // Obtains the current reading and stores to adc_code variable // Convert adc_code to voltage adc_voltage = LTC2378_code_to_voltage(adc_code, vref);
