The following parts (DUT) are pin-compatible, 16-bit A/D converters with serial I/O, and an internal reference:
9
LTC2381-16: 16-Bit, 250Ksps ADC.
10
LTC2382-16: 16-Bit, 500Ksps ADC.

Read ADC input.
16
17
LTC2383_read(LTC2383_CS, &adc_code); // Throws out last reading
18
LTC2383_read(LTC2383_CS, &adc_code); // Obtains the current reading and stores to adc_code variable
19
20
// Convert adc_code to voltage
21
adc_voltage = LTC2383_code_to_voltage(adc_code, vref);
