具有内部参考的 2.7V 至 5.5V 10 位 8 通道串行 DAC
8-Channel, 12-/10-/8-Bit, 2.7-V to 5.5-V, Low Power DAC with Power Down
说明
The TLV5630, TLV5631, and TLV5632 are pin-compatible,eight-channel, 12-/10-/8-bit voltage output DACs each with a flexible serial interface. The serial interface allows glueless interface to TMS320 and SPI, QSPI, and Microwire serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits.
Additional features are a power-down mode, an LDAC input for simultaneous update of all eight DAC outputs, and a data output which can be used to cascade multiple devices, and an internal programmable band-gap reference.
The resistor string output voltage is buffered by a rail-to-rail output amplifier with a programmable settling time to allow the designer to optimize speed vs power dissipation. The buffered, high-impedance reference input can be connected to the supply voltage.
Implemented with a CMOS process, the DACs are designed for single-supply operation from 2.7 V to 5.5 V, and can operate on two separate analog and digital power supplies. The devices are available in 20-pin SOIC and TSSOP packages.

供应TI 的高效升压降压转换器IC TPS63000DRCR
信息内容：TI 的具有 1.8A 电流开关的 96% 升压降压转换器IC TPS63000DRCR 半导体 > 电源管理 > 开关稳压器 > DC/DC 转换器（集成开关） > 升压 - 降压稳压器 > TPS63000 High Efficient Single Inductor Buck-Boost Converter with 1.8-A Switch 说明 The TPS6300x devices provide a power supply solution forproducts powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 1200 mA while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to maintain high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is ...
供应极低功耗全差动放大器IC THS4521IDr/IDGK
信息内容：德州仪器的极低功耗轨至轨输出全差动放大器集成电路 THS4521ID 和 THS4521IDGK Very Low Power, Negative Rail Input, Rail-to-Rail Output, Fully Differential Amp 说明 The THS4521, THS4522, and THS4524 family of devices are very low-power, fully differential op amps with rail-to-rail output and an input common-mode range that includes the negative rail. These amplifiers are designed for low-power data acquisition systems and high-density applications where power dissipation is a critical parameter, and provide exceptional performance in audio applications. The family includes single (THS4521), dual (THS4522), and quad (THS4524) versions. These fully differential op amps feature accurate output common-mode control that allows for dc-coupling when driving analog-to-digital converters (ADCs). This control, coupled with an input common-mode range below the negative rail as well as rail-to-rail output, allows for easy interfacing between single-ended, ground-referenced signal sou...
