  Product Overview The OPAx991 family (OPA991, OPA2991, and OPA4991) is a family of high voltage (40 V) general purpose operational amplifiers. These devices offer exceptional DC precision and AC performance, including rail-to-rail input/output, low offset ( ± 125 µV, typical), low offset drift ( ± 0.3 µV/ ° C, typical), low noise (10.5 nV/ √ Hz and 1.8 µVPP), and 4.5-MHz bandwidth.   This blog will introduce OPA2991IDR systematically from its features, pinout to its specifications, applications, also including OPA2991IDR datasheet and so much more.   OPA2991IDR Features • Low offset voltage: ± 125 µV • Low offset voltage drift: ± 0.3 µV/ ° C • Low noise: 10.8 nV/ √ Hz at 1 kHz • High common-mode rejection: 130 dB • Low bias current: ± 10 pA • Rail-to-rail input and output • Wide bandwidth: 4.5 MHz GBW • High slew rate: 21 V/µs • High capacitive load drive: 1 nF • MUX-friendly/comparator inputs – Amplifier operates with differential inputs up to   supply rail – Ampl...

USB3320C-EZK USB Interface IC Datasheet

Image
  Product Overview The USB3320C-EZK is a highly integrated full featured high-speed USB 2.0 ULPI Transceiver based on Microchip's proven ULPI interface. The high-speed USB 2.0 transceiver provides a configurable physical layer (PHY) solution and is an excellent match for a wide variety of products. The frequency of the reference clock is user selectable. The USB3320 includes an internal oscillator that may be used with either a quartz crystal or a ceramic resonator. Alternatively, the crystal input can be driven by an external clock oscillator. Another option is the use of a 60MHz external clock when using the ULPI input clock mode. Several advanced features make the USB3320 the transceiver of choice by reducing both electrical bill of material (eBOM) part count and printed circuit board (PCB) area. Outstanding ESD robustness eliminates the need for external ESD protection devices in typical applications. The internal over-voltage protection circuit (OVP) protects the USB3320 from...

LD1117V33 Voltage Regulators Datasheet PDF

Image
Product Overview The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version (VREF = 1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.3 V and 5.0 V. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220. The SOT-223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. In fact in this case, unlike than PNP one, the quiescent current flows mostly into the load. Only a very common 10 µF minimum capacitor is needed for stability. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1 % at 25 ° C. The adjustable LD1117 is pin to pin compatible with the other standard. Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.   This blog will introduce LD1117V33 sy...
