The AD8418 is a high voltage, high resolution current shunt amplifier. It features an initial gain of 20 V/V, with a maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8418 offers excellent input common-mode rejection from −2 V to +70 V. The AD8418 performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, battery management, and solenoid control.

he AD8418 offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zero drift core, which leads to a typical offset drift of 0.1 µV/°C throughout the operating temperature range and the common-mode voltage range. The AD8418 is fully qualified for automotive applications and includes EMI filters and patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages. The typical input offset voltage is ±200 µV. The AD8418 is offered in 8-lead MSOP and SOIC packages.

The MAX2870ETJ+ is a 23.5MHz to 6000MHz fractional/ integer-N synthesizer/VCO in 32 pin TQFN package. This high performance ultra wideband phase locked loop (PLL) with integrated voltage control oscillator (VCO) is capable of operating in both integer-N and fractional-N modes. The MAX2870 is capable of synthesizing frequencies from 23.5MHz to 6GHz while maintaining superior phase noise and spurious performance when combined with an external reference oscillator and loop filter. The ultra wide frequency range is achieved with help of multiple integrated VCOs covering 3000MHz to 6000MHz and output dividers ranging from 1 to 128. The device also provides dual differential output drivers which can be independently programmable to deliver -4dBm to +5dBm output power. Both outputs can be muted by either software or hardware control. The MAX2870 is used in test and measurement, satellite communications and PMAR/LMAR/public safety radio.
