The following parts (DUT) are pin-compatible, 16/18-bit A/D converters with serial I/O, and an internal reference:
LTC2364-16: 16-Bit, 250Ksps ADC
LTC2364-18: 18-Bit, 250Ksps ADC
LTC2367-16: 16-Bit, 500Ksps ADC
LTC2367-18: 18-Bit, 500Ksps ADC
LTC2368-16: 16-Bit, 1Msps ADC
LTC23678-18: 18-Bit, 1Msps ADC
LTC2369-18: 18-Bit, 1.6Msps ADC
LTC2370-16: 16-Bit, 2Msps ADC

Example Code:

Read ADC input.

    LTC2370_read(LTC2370_CS, &adc_code);   // Throws out last reading
    LTC2370_read(LTC2370_CS, &adc_code);   // Obtains the current reading and stores to adc_code variable

    // Convert adc_code to voltage
    adc_voltage = LTC2370_code_to_voltage(adc_code, vref);
