AD7878LN Description

Short technical summary and product information.

The AD7878LN is a fast, complete 12-bit analog-to-digital converter from Analog Devices, designed for high-speed DSP interface applications. The device integrates a track/hold amplifier with 2 µs acquisition time, a 7 µs (typical) successive-approximation ADC, an internal 3 V Zener reference, and an 8-word FIFO memory with associated control logic.

 

Key electrical specifications include a sampling rate of 100 kHz, a single-ended ±3 V input voltage range, and a signal-to-noise ratio of 70 dB minimum (at 10 kHz input frequency). The converter achieves a maximum total harmonic distortion of -80 dB and guarantees no missing codes at 12-bit resolution. The device operates from +5 V and -5 V supplies with a typical power dissipation of 60 mW.

 

The ADC also includes an internal reference and logic that interfaces directly to high-speed DSP processors such as the ADSP-2100 or TMS32010. The device is available in a 28-lead DIP (0.600" width, 15.24mm pitch) package and is intended for through-hole mounting. The L version operates over a 0°C to 70°C temperature range.
