The document describes an 8-bit pipelined analog-to-digital converter (ADC) with a selectable resolution of 5-8 bits. The ADC was fabricated in a 0.13-micron CMOS process and achieves an effective number of bits of 6.10 in 8-bit mode with a 162 MHz input signal. Key aspects of the ADC include double sampling to relax amplifier settling times, redundant sign digit correction to compensate comparator offsets, and a two-stage op-amp design to provide sufficient gain and signal headroom given the low 1.2V supply voltage. Measured performance meets the requirements for medium resolution and sampling rate ADCs in modern synthetic aperture radar systems.
1. The document describes the VIPer22A, a low power offline SMPS primary switcher integrated circuit that combines a current mode PWM controller with a high voltage power MOSFET.
2. The VIPer22A has a wide input voltage range of 85-265V, output power capabilities of 7-20W, and a fixed switching frequency of 60kHz.
3. It features current mode control, undervoltage lockout, overtemperature protection, and can accommodate supply voltages from 9-38V on its VDD pin.
The document discusses LED driver ICs for MR16 lamps, including the NCL30160 and NCL30161. It provides a decision tree to select the appropriate LED driver based on input voltage, output current and other factors. The NCL30160 and NCL30161 are then described in more detail, highlighting their constant current driving ability, integrated MOSFET, dimming functionality and other features. Application examples and performance data are also provided.

Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
1. PCA9532
16-bit I2C-bus LED dimmer
Rev. 04 — 17 March 2009 Product data sheet
1. General description
The PCA9532 is a 16-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in
256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.
The PCA9532 contains an internal oscillator with two user programmable blink rates and
duty cycles coupled to the output PWM. The LED brightness is controlled by setting the
blink rate high enough (> 100 Hz) that the blinking cannot be seen and then using the duty
cycle to vary the amount of time the LED is on and thus the average current through the
LED.
The initial setup sequence programs the two blink rates/duty cycles for each individual
PWM. From then on, only one command from the bus master is required to turn individual
LEDs ON, OFF, BLINK RATE 1 or BLINK RATE 2. Based on the programmed frequency
and duty cycle, BLINK RATE 1 and BLINK RATE 2 will cause the LEDs to appear at a
different brightness or blink at periods up to 1.69 second. The open-drain outputs directly
drive the LEDs with maximum output sink current of 25 mA per bit and 200 mA per
package (100 mA per octal).
To blink LEDs at periods greater than 1.69 second the bus master (MCU, MPU, DSP,
chip set, etc.) must send repeated commands to turn the LED on and off as is currently
done when using normal I/O expanders like the NXP Semiconductors PCF8575 or
PCA9555. Any bits not used for controlling the LEDs can be used for General Purpose
parallel Input/Output (GPIO) expansion, which provides a simple solution when additional
I/O is needed for ACPI power switches, sensors, push-buttons, alarm monitoring, fans,
etc.
The active LOW hardware reset pin (RESET) and Power-On Reset (POR) initializes the
registers to their default state, all zeroes, causing the bits to be set HIGH (LED off).
Three hardware address pins on the PCA9532 allow eight devices to operate on the same
bus.
