Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 Fax: 617/326-8703 FEATURES Differential Amplification Wide Common-Mode Voltage Range: +12.8 V, –12 V Differential Voltage Range: 2 V High CMRR: 60 dB @ 4 MHz Built-in Differential Clipping Level: 2.3 V Fast Dynamic Performance 85 MHz Unity Gain Bandwidth 35 ns Settling Time to 0.1% 360 V/ s Slew Rate Symmetrical Dynamic Response Excellent Video Specifications Differential Gain Error: 0.06% Differential Phase Error: 0.08 15 MHz (0.1 dB) Bandwidth Flexible Operation High Output Drive of 50 mA min Specified with Both 5 V and 15 V Supplies Low Distortion: THD = –72 dB @ 4 MHz Excellent DC Performance: 3 mV max Input Offset Voltage APPLICATIONS Differential Line Receiver High Speed Level Shifter High Speed In-Amp Differential to Single Ended Conversion Resistorless Summation and Subtraction High Speed A/D Driver PRODUCT DESCRIPTION The AD830 is a wideband, differencing amplifier designed for use at video frequencies but also useful in many other applica- tions. It accurately amplifies a fully differential signal at the FREQUENCY – Hz 110 30 10M 50 40 1k 70 60 80 90 100 1M 100k 10k V S = ±15V V S = ±5V Common-Mode Rejection Ratio vs. Frequency input and produces an output voltage referred to a user-chosen level. The undesired common-mode signal is rejected, even at high frequencies. High impedance inputs ease interfacing to fi- nite source impedances and thus preserve the excellent common-mode rejection. In many respects, it offers significant improvements over discrete difference amplifier approaches, in particular in high frequency common-mode rejection. The wide common-mode and differential-voltage range of the AD830 make it particularly useful and flexible in level shifting applications, but at lower power dissipation than discrete solu- tions. Low distortion is preserved over the many possible differ- ential and common-mode voltages at the input and output. Good gain flatness and excellent differential gain of 0.06% and phase of 0.08 ° make the AD830 suitable for many video system applications. Furthermore, the AD830 is suited for general pur- pose signal processing from dc to 10 MHz. 9 –6 –21 100k 1G 10M 1M 10k –3 0 3 6 –18 –15 –12 –9 FREQUENCY – Hz 100M V S = ±5V R L = 150Ω C L = 4.7pF C L = 15pF C L = 33pF Closed-Loop Gain vs. Frequency, Gain = +1 |
