The ADA8282 is designed for applications that require low cost, low power, compact size, and flexibility. The ADA8282 has four parallel channels, each including a low noise preamplifier (LNA) and a programmable gain amplifier (PGA). The LNA and PGA combine to form a signal chain that features a gain range of 18 dB to 36 dB in 6 dB increments with a guaranteed minimum bandwidth of 5 MHz.Using the highest power settings, the combined input referred voltage noise of the combined LNA and PGA channel is 3.4 nV/?Hz at maximum gain. The ADA8282 can be configured in four power modes that trade off power and noise performance to optimize the performance according to the end application. Fabricated in an advanced complementary metal-oxide semiconductor (CMOS) process, the ADA8282 is available in a 5 mm ? 5 mm, RoHS-compliant, 32-lead LFCSP. It is specified over the automotive temperature range of ?40?C to +125?C.

Demonstration circuit 2091A is optimized for evaluation of the LTC5599 low power direct quadrature modulator. The balanced I and Q baseband input ports can be either AC- or DC-coupled to a source with a common mode voltage level of about 1.4V. Fixed LC networks on the LO and RF ports cover a continuous 90MHz to 1300MHz range. The SPI interface controls the supply current, modulator gain, and allows optimization of the LO carrier feedthrough and side-band suppression.

The ADM7171 is a CMOS, low dropout linear regulator (LDO) that operates from 2.3 V to 6.5 V and provides up to 1 A of output current. This high output current LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 6 V down to 1.2 V rails. Using an advanced proprietary architecture, the device provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7 ?F ceramic output capacitor. Load transient response is typically 1.5 ?s for a 1 mA to 500 mA load step.The ADM7171 is available in 17 fixed output voltage options. The following voltages are available from stock: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V.

HDQ Protocol Implementation with MSP430 Application Report

The LT6118 is a complete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference and a latching comparator. The comparator latch functionality can be enabled or disabled and the comparator can be configured to reset upon power-on. The input and the open-drain output of the comparator are independent from the current sense amplifier. The comparator trip point and amplifier gain are configured with external resistors.The overall propagation delay of the LT6118 is typically only 1.4?s, allowing for quick reaction to overcurrent conditions. The 1MHz bandwidth allows the LT6118 to be used for error detection in critical applications such as motor control. The high threshold accuracy of the comparator, combined with the ability to latch the comparator, ensures the LT6118 can capture high speed events.The LT6118 is fully specified for operation from ?40?C to 125?C, making it suitable for industrial and automotive applications.
