DC1620A-M: Demo Board for LTC2145-12 12-Bit, 125Msps Low Power Dual ADCs.

The LTC2655 is a family of Quad I2C 16-/12-Bit Rail-to-Rail DACs with integrated 10ppm/?C max reference. The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2655-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2655-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage.The parts use the 2-wire I2C compatible serial interface. The LTC2655 operates in both the standard mode (maximum clock rate of 100kHz) and the fast mode (maximum clock rate of 400kHz). The LTC2655 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs power-on reset to zero-scale. If PORSEL is tied to VCC, the DACs power-on reset to mid-scale.Applications Mobile Communications Process Control and Industrial Automation Instrumentation Automatic Test Equipment Automotive

The LTC1286/LTC1298 are micropower, 12-bit, successive approximation sampling A/D converters. They typically draw only 250?A of supply current when converting and automatically power down to a typical supply current of 1nA whenever they are not performing conversions. They are packaged in 8-pin SO packages and operate on 5V to 9V supplies. These 12-bit, switched-capacitor, successive approximation ADCs include sample-and-holds. The LTC1286 has a single differential analog input. The LTC1298 offers a software selectable 2-channel MUX.On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers over three wires. This, coupled with micropower consumption, makes remote location possible and facilitates transmitting data through isolation barriers.These circuits can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans (to 1.5V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.Applications Battery-Operated Systems Remote Data Acquisition Battery Monitoring Handheld Terminal Interface Temperature Measurement Isolated Data Acquisition

The LTC2486 is a 4-channel (2-channel differential), 16-bit, No Latency ??? ADC with Easy Drive? technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2486 includes programmable gain, a high accuracy temperature sensor, and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 4 analog input channels operating in single ended or differential modes) or its internal temperature sensor. It can be programmed to reject line frequencies of 50Hz, 60Hz, or simultaneous 50Hz/60Hz, provide a programmable gain from 1 to 256 in 8 steps, and configured to double its output rate. The integrated temperature sensor offers 1/2?C resolution and 2?C absolute accuracy. The LTC2486 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel selection is valid.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control
