AD8115AST Descrizione generale

The AD8115AST is a high-performance video amplifier that offers exceptional signal processing capabilities for video distribution systems and high-speed applications. With a 300 MHz bandwidth and a slew rate of 900 V/µs, this amplifier is well-suited for demanding video applications where low distortion and fast settling time are crucial

Caratteristiche principali

16 × 16 high speed nonblocking switch arrays: G = 2
Serial or parallel programming of switch array
Serial data out allows daisy-chaining of multiple 16 × 16 arrays to create larger switch arrays
High impedance output disable allows connection of
multiple devices without loading the output bus
For smaller arrays see the AD8108/AD8109 (8 × 8) or AD8110/AD8111 (16 × 8) switch arrays
Complete solution
Buffered inputs

25 MHz, 0.1 dB gain flatness
0.05%/0.05° differential gain/differential phase error (R
L
Excellent ac performance
Slew rate: 375 V/μs
Low power of 700 mW (2.75 mW per point)
Low all hostile crosstalk of ?70 dB at 5 MHz
Reset pin allows disabling of all outputs (connected through a capacitor to ground provides power-on reset capability)
100-lead LQFP (14 mm × 14 mm)

Applicazione

The differential gain and differential phase of better than 0.05%and 0.05°, respectively, along with a 0.1 dB flatness out to 25 MHzwhile driving a 75 ? back-terminated load, make the AD8114/AD8115 ideal for all types of signal switching.
The AD8114/AD8115 include 16 independent output buffersthat can be placed into a high impedance state for parallelingcrosspoint outputs so that off channels do not load the output bus.The AD8114 has a gain of 1, while the AD8115 offers a gain of 2.They operate on voltage supplies of ±5 V while consuming only70 mA of idle current. The channel switching is performed via aserial digital control (which can accommodate daisy-chaining ofseveral devices) or via a parallel control, allowing updating of anindividual output without reprogramming the entire array.
The AD8114/AD8115 is packaged in a 100-lead LQFP and isavailable over the extended industrial temperature range of?40°C to +85°C.
