The AD7878JN is a complete 12-bit analog-to-digital converter from Analog Devices designed for high-speed DSP applications. It integrates a track-and-hold amplifier with 2 µs acquisition time, a 7 µs A/D converter, a 3 V Zener reference, and an 8-word FIFO memory with control logic.
Key electrical specifications include a 100 kHz sampling rate, ±3 V bipolar input range, 41 ns maximum data access time, and typical power dissipation of 60 mW. The device achieves 72 dB signal-to-noise ratio (SNR) at a 10 kHz input frequency.
The ADC interfaces to DSP processors via SPI or DSP-compatible protocols, supporting direct connection to devices such as ADSP-2100, TMS32010, and TMS32020. The FIFO allows up to eight conversions to be stored before processor intervention is required.
Packaged in a 28-lead PDIP (0.600", 15.24mm) with through-hole mounting, the AD7878JN operates over a 0°C to 70°C temperature range. It is suitable for digital signal processing, speech recognition, spectrum analysis, and high-speed modem applications.
The AD7878JN has 12-bit resolution.
The sampling rate is 100 kHz.
The analog input voltage range is ±3 V bipolar.
The AD7878JN supports SPI and DSP data interfaces.
The operating temperature range is 0°C to 70°C.
The AD7878JN is available in a 28-PDIP package (28-DIP, 0.600", 15.24mm).
The RoHS status is listed as RoHS3 Compliant but is unverified.
