Common-Mode Rejection Ratio vs. Frequency High speed level shifter High speed in-amp Differential to single-ended conversion Good gain flatness and excellent differential gain of 0.06% and Resistorless summation and subtraction phase of 0.08° make the AD830 suitable for many video system High speed analog-to-digital converter applications. Furthermore, the AD830 is suited for general-purpose signal processing from dc to 10 MHz. GENERAL DESCRIPTION 9 VS = ±5V The AD830 is a wideband, differencing amplifier designed for use 6 RL = 150Ω at video frequencies but also useful in many other applications. It 3 accurately amplifies a fully differential signal at the input and CL = 33pF 0 produces an output voltage referred to a user-chosen level. The –3 undesired common-mode signal is rejected, even at high dB) CL = 4.7pF frequencies. High impedance inputs ease interfacing to finite N ( –6 AI source impedances and, thus, preserve the excellent common- G –9 mode rejection. In many respects, it offers significant –12 improvements over discrete difference amplifier approaches, in CL = 15pF –15 particular in high frequency common-mode rejection. –18 The wide common-mode and differential voltage range of the –21 AapDp8li3ca0t imonaks eb uitt p aat rltoicwuelra rploy wueser fduils asinpda tfiloenxi tbhlea nin d liesvcerle tseh isfotiluntgi ons. 10k 100k F1RMEQUENCY 1(0HMz) 100M 1G 00881-003 Figure 3.

Data Sheet AD830 ABSOLUTE MAXIMUM RATINGS MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the Table 3. AD830 is limited by the associated rise in junction temperature. Parameter Rating For the plastic packages, the maximum safe junction Supply Voltage ±18 V temperature is 145°C. For the CERDIP, the maximum junction Internal Power Dissipation Observe derating temperature is 175°C. If these maximums are exceeded curves momentarily, proper circuit operation will be restored as soon Output Short-Circuit Duration Observe derating as the die temperature is reduced. Leaving the AD830 in the curves overheated condition for an extended period can result in Common-Mode Input Voltage ±VS permanent damage to the device. To ensure proper operation, it Differential Input Voltage ±VS is important to observe the recommended derating curves. Storage Temperature Range (Q) −65°C to +150°C While the AD830 output is internally short-circuit protected, Storage Temperature Range (N) −65°C to +125°C this may not be sufficient to guarantee that the maximum Storage Temperature Range (RN) −65°C to +125°C junction temperature is not exceeded under all conditions. If Operating Temperature Range the output is shorted to a supply rail for an extended period, AD830J 0°C to +70°C then the amplifier may be permanently destroyed. AD830A −40°C to +85°C AD830S −55°C to +125°C THERMAL RESISTANCE Lead Temperature Range (Soldering 60 sec) 300°C θ is specified for the worst-case conditions, that is, a device JA Stresses at or above those listed under Absolute Maximum soldered in a circuit board for surface-mount packages.
