ZN425E8, 8-BIT D-A/A-D CONVERTER

ZN425E8 8-BIT D-A/A-D CONVERTER MAY 1994 DS3005-2.0 The ZN425 is a monolithic 8-bit D-A converter containing an R-2R ladder network of diffused resi.

Features

* s ±1/2 LSB Linearity Error s 0°C to +70°C s TTL and 5V CMOS Compatible s Single +5V Supply s Settling Time (D-A) 1µs Typical s Conversion Time (A-D) 1ms Typical, using Ramp and Compare Technique s Extra Components Required D-A: Reference Capacitor (Direct Voltage Output through 10kOhms Typ. ) A-D: Co

Applications

* the source resistance to the inverting input of the operational ampliﬁer should be approximately 6kΩ. The calibration procedure is as follows: i. Set all bits to OFF (low) and adjust R2 until VOUT = 0.000V. ii. Set all bits to ON (high) and adjust R1 until VOUT = Nominal full-scale reading - 1LSB
