Description

The ADS8864 is a 16-bit, 400-kSPS, single-ended input, analog-to-digital converter (ADC).
The device operates with a 2.5-V to 5-V external reference, offering a wide selection of signal ranges without additional input signal scaling. The reference voltage setting is independent of, and can exceed, the analog supply voltage (AVDD).

The device offers an SPI-compatible serial interface that also supports daisy-chain operation for cascading multiple devices. An optional busy-indicator bit makes synchronizing with the digital host easy.

Features

1. Sample rate: 400 kHz

2. No latency output

3. Unipolar, single-ended input range : 0 to +VREF

4. SPI-compatible serial interface with daisy-chain option

5. Low-power dissipation :

(1) 2.6 mW at 400 kSPS

(2) 0.65 mW at 100 kSPS

 

Applications:

1. Automatic test equipment (ATE)

2. Instrumentation and process controls

3. Precision medical equipment

4. Low-power, battery-operated instruments

Part Number: LM3554

Function: Synchronous Boost Converter with 1.2A Dual High Side LED Drivers and I2C Compatible Interface

Package: 16 Bump μSMD Type

Manufacturer: Texas Instruments

Description

The LM3554 is a 2MHz fixed frequency, current mode synchronous boost converter. The device is designed to operate as a dual 600mA (1.2A total) constant-current driver for high-current white LEDs, or as a regulated 4.5V or 5V voltage source.

The dual high-side current sources allow for grounded cathode LED operation. An adaptive regulation method ensures the current source for each LED remains in regulation and maximizes efficiency.

Features

1. Dual High Side Current Sources

2. Grounded Cathode Allowing for Better Heatsinking and LED Routing

3. >90% Efficiency

4. Ultra-Small Solution Size: < 23mm2

5. Four Operating Modes: Torch, Flash, LED Indicator and Voltage Output

6. Accurate and Programmable LED Current from 37.5mA to 1.2A

Applications:

• Camera Phone LED Flash Controller

• Class D Audio Amplifier Power

• LED Current Source Biasing
