AD7820LR IC ADC 8BIT HS TRACK/HOLD 20SOIC

These are new and not used -- in manufacturer's original packaging. Very nice.

AD7821KR High Speed, uP-Compatible 8-Bit ADC with Track/Hold Function by Analog Devices

DESCRIPTION: The AD7821 is a high speed, 8-bit, sampling, analog-to-digital converter that offers improved performance over the popular AD7820. It offers a conversion time of 660 ns (vs. 1.36 ms for the AD7820) and 100 kHz signal bandwidth (vs. 6.4 kHz).

The AD7821 is fabricated in Linear-Compatible CMOS (LC2MOS), an advanced, mixed technology process combining precision bipolar circuits with low power CMOS logic. The part features a low power dissipation of 50 mW.

• Fast Conversion Time: 660 ns max
• 100 kHz Track-and-Hold Function
• 1 MHz Sample Rate
• Unipolar and Bipolar Input Ranges
• Ratiometric Reference Inputs
• No External Clock
• Extended Temperature Range Operation

These parts are new and unused.
