The AD1385TD is a complete 16-bit, 500 kHz sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features differential linearity autocalibration to eliminate DNL drift over temperature, ensuring outstanding noise and distortion performance. The device specifies an SNR of 90 dB at 100 kHz and THD of -88 dB at 100 kHz. It supports ±5 V and ±10 V bipolar input ranges with no missing codes. Typical specifications include 0.0006% FSR DNL and 0.0015% FSR INL. The component operates over a wide military temperature range from –55°C to +125°C.
The AD1385 belongs to the AD138x family of high-resolution sampling ADCs from Analog Devices. It is designed for applications requiring high accuracy and stability across extreme temperatures. The 'TD' suffix typically denotes a specific package and temperature grade variant within this product line, distinct from other pinouts or commercial grades in the series.
