AD1385 is a 16-bit 500 kHz wide temperature range sampling ADC with differential linearity autocalibration feature, which offers outstanding noise and distortion performance, as well as excellent INL and DNL specifications, over the full military temperature range.
The AD1385 is a complete 500 kHz, 16-bit sampling analog-to-digital converter contained in a single package. It features differential linearity autocalibration and zero offset autocalibration to ensure outstanding noise and distortion performance over the full military temperature range of -65°C to +125°C.
The device architecture includes a low noise, low distortion track/hold, a three pass digitally corrected subranging ADC, and linearity calibration circuitry. It operates with four power supplies (+5 V, +10 V, +15 V, -15 V) and an external 10 MHz clock.
