CD4541B datasheet

Description

The CD4541B programmable timer consists of a 16-stage binary counter, an oscillator that is controlled by external R-C components (2 resistors and a capacitor), an automatic power-on reset circuit, and output control logic. The counter increments on positive-edge clock transitions and can also be reset via the MASTER RESET input.

Features

1. Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V
2. Built-In Low-Power RC Oscillator
3. Oscillator Frequency Range : DC to 100kHz
4. External Clock (Applied to Pin 3) can be Used Instead of Oscillator
5. Operates as 2N Frequency Divider or as a Single-Transition Timer
6. Q/Q Select Provides Output Logic Level Flexibility
7. AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation
8. Operates With Very Slow Clock Rise and Fall Times

ADS8684 Datasheet – 16 Bit, 4-Channel, SAR ADC ( PDF )

Posted on by pinout

Part Number: ADS8684

Function: SAR ADC with 16 bits, 4 channels, 500 kSPS, and bipolar inputs off +5V supply

Package: TSSOP 38 Pin Type

Manufacturer: Texas Instruments

Pinouts:
ADS8684 datasheet

Description

The ADS8684 and ADS8688 are 4- and 8-channel, integrated data acquisition systems based on a 16-bit successive approximation (SAR) analog-to-digital converter (ADC), operating at a throughput of 500 kSPS. The devices feature integrated analog front-end circuitry for each input channel with overvoltage protection up to ±20 V, a 4- or 8-channel multiplexer with automatic and manual scanning modes, and an on-chip, 4.096-V reference with low temperature drift.
