Product Summary
The AD389 is complete with an internal hold capacitor and it incoporates a compensation network which minimizes the sample to hold charge offset.
Typical applications for the AD389 include sampled data systems, peak hold functions, strobed measurement systems and simultaneous sampling converter systems. When used with autozero and autocalibration techniques, this T/H combined with a high linerity A/D will offer 14-bit performance over the converter's full no-missing-code temperature range.
Version"K" is commercial temperature range 0 to +70°C
Version "B" is commercial industrial range -25°C to +85°C.
Parametrics
The device AD389 is available in two versions:
the "K" specified for operation over the 0 to +70°C commercial temperature range.
the "B" specified over the full industrial temperature range, -25°C to +85°C.
Features
The features of AD389KD can be summarized as (1)Companion to High Resolution A/D Converters; (2)Fast Acquisition Time: 2.5μs to ±0.003%; (3)Low Droop Rate: 0.1μV/μs; (4)Aperture Jitter: 400ps; (5)Internal Hold Capacitor; (6)Unity Gain Inverter; (7)Low Power Dissipation: 300mW.
