The ADA4858-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies to output negative voltages or output a 0 V level for video applications. The 600 MHz, ?3 dB bandwidth and 600 V/?s slew rate make this amplifier well suited for many high speed applications. In addition, its 0.1 dB flatness out to 85 MHz at G = 2, along with its differential gain and phase errors of 0.01% and 0.02? into a 150 ? load, make it well suited for professional and consumer video applications.This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2.5 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at ?3 V. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at a 5 V supply.The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the extended industrial temperature range of ?40?C to +105?C.ApplicationsProfessional videoConsumer videoImagingActive filtersData Sheet, Rev.

The ADL5206 is a wide bandwidth, variable gain amplifier (VGA) with digital control (also known as a digital gain amplifier (DGA)) that provides precise gain control, high output third-order intercept (OIP3), and low noise figure over the entire gain range. The excellent OIP3 performance of 39.4 dBm (at 300MHz, 5 V supply, and maximum gain) makes the ADL5206 an excellent gain control device for a variety of receiver applications. For wide input dynamic range applications, the ADL5206 provides a broad 2 dB to 32 dB gain range with a 1 dB step size. The gain is adjustable through multiple gain control and interface options: parallel, serial peripheral interface (SPI), or gain step-up and step-down controls. The ADL5206 can be powered up independently by applying the appropriate logic level to the PWUP pin. The quiescent current of the ADL5206 is typically 112 mA with a 5 V supply. When disabled, the ADL5206 consumes only 8 mA and offers excellent input to output isolation. The gain setting is preserved when the device is disabled.

The ADL5304 is a high speed logarithmic converter with fast response and low noise over a 200 dB (1 pA to 10 mA) measurement range. The ADL5304 provides a nominal logarithmic slope of 10 mV/dB (200 mV/decade); other values are easily configured. Logarithmic intercept can be programmed over a wide range with the internal 100 nA current source or externally for log ratio applications.The default intercept value of 3.162 fA places the midpoint of the measurement range of 100 nA at VLOG = 1.5 V.A single positive supply of 5 V is all that is required for operation over a specified 1 pA to 3 mA input range. Dual-supply operation extends the specified input current range to 10 mA.The ADL5304 accepts two current inputs to the logarithmic argument. The numerator input, INUM, flows in the collector of an NPN transistor, connected in a feedback path around a low offset JFET amplifier. The denominator current, IDEN, is treated in the same way, which allows for log ratio operation. The input summing nodes (INUM and IDEN) operate at a constant default voltage of 1.5 V. The VSM1 to VSM4 pins flank the INUM and IDEN inputs to provide a guard voltage to minimize leakage currents.Adaptive photodiode biasing is provided for optical measurements. A monitor current 1.1 times INUM is output at the IMON pin, and an external resistor, RMNTR, at 10 times the photodiode series resistance (RS) applies a voltage across the photodiode that 1st order keeps the internal PD junction at 0 V to minimize dark current.The VLOG output is buffered and can be rescaled through internal gain setting resistors. The internal ILOG varies from ?400 ?A to +400 ?A as INUM changes over 10 decades from 1 pA to 10 mA. This corresponds to 0.5 V to 2.5 V at the VLOG pin in the default configuration shown in Figure 1.Accurate 1.5 V (Pin 1P5V) and 2.0 V (Pin 2VLT) reference outputs allow precise repositioning of the intercept using external resistors.The ADL5304 is available in a 32-lead, 5 mm ? 5 mm LFCSP and specified for operation from ?40?C to +85?C.Applications High accuracy optical power measurement Wide range baseband log compression Versatile detector for high speed APC loops
