The ADC0808M is a monolithic CMOS device with an 8-channel multiplexer, an 8-bit analog-to-digital (A/D) converter, and microprocessor-compatible control logic.

The ADC0803 and ADC0805 are CMOS 8-bit successive-approximation analog-to-digital converters that use a modified potentiometric (256R) ladder. They feature 8-bit resolution, ratiometric conversion, 100-µs conversion time, 135-ns access time, guaranteed monotonicity, high reference ladder impedance, no zero adjust requirement, on-chip clock generator, single 5-V power supply, and can operate with a microprocessor or as a stand-alone device.

LP111, LP211 and LP311 are low-power versions of the industry standard LM111, LM211, LM311. They take advantage of stable, high-value, ion-implanted resistors to perform the same function as the LM311 series, with a 30:1 reduction in power consumption but only a 6:1 slowdown in response time. They are well suited for battery-powered applications and all other applications where fast response times are not needed. They operate over a wide range of supply voltages, from ±18V down to a single 3-V supply with less than 300-µA current drain, but are still capable of driving a 25-mA load. If ordinary precautions are taken to minimize stray coupling from the output to either input or to the trim pins, the LP111, LP211, and LP311 are quite easy to apply free of oscillation. The LP111 is characterized for operation over the full military temperature range, from −55°C to +125°C, and is guaranteed to operate within specifications in this temperature range.

The LM317 is a three-terminal adjustable positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.2 V to 37 V.

The TLC04/MF4A-50 and TLC14/MF4A-100 are monolithic Butterworth low-pass switched-capacitor filters. Each is designed as a low-cost, easy-to-use device providing accurate fourth-order low-pass filter functions in circuit design configurations. Each filter features cutoff frequency stability that is dependent only on the external-clock frequency stability. The cutoff frequency is clock tunable and has a clock-to-cutoff frequency ratio of 50:1 with less than ±0. 8% error for the TLC04/MF4A-50 and a clock-to-cutoff frequency ratio of 100:1 with less than ±1% error for the TLC14/MF4A-100. The input clock features self-clocking or TTL- or CMOS-compatible options in conjunction with the level shift (LS) terminal.

TLC04 is a voltage amplifier that provides high gain and low input bias current.

The bq2063 SBS v1.1-compliant Li-Ion gas gauge IC provides accurate measurement of available charge in Li-Ion batteries. It supports the 2-Wire SMBus V1.1 interface with PEC or Single-Wire HDQ16. It directly interfaces the Seiko S-8243 protection IC for maximum safety protection and minimal component count. It supports internal or external thermistor and reports individual cell voltages. It uses a 15-Bit ADC for accurate voltage, temperature, and current measurements. It consumes less than 0.5 mW operating power and drives a 4- or 5-segment LED display for remaining capacity indication.

The bq2058t lithium ion pack supervisor is a low cost lithium ion battery pack supervisor that protects and monitors two lithium ion series cells for overvoltage, undervoltage, and monitors pack for overcurrent.

bq2058t lithium ion pack supervisor is a device to control charge and discharge cell voltage limits for two lithium ion (li-ion) series cells, accommodating battery packs containing series/parallel configurations. the low operating current does not overdischarge the cells during periods of storage and does not significantly increase the system discharge load. bq2058t can be part of a low-cost li-ion charge control system within the battery pack. bq2058t controls two external fets to limit the charge and discharge potentials. bq2058t allows charging when each individual cell voltage is below vov (overvoltage limit). if the voltage on any cell exceeds vov for a user-configurable delay period (tOVD), the open-drain chg pin goes to the high-impedance state, shutting off charge to the battery pack. this safety feature prevents overcharge of any cell within the battery pack. after an over-voltage condition occurs, each cell must fall below vce (charge enable voltage) for the bq2058t to re-enable charging. bq2058t is a low-cost, low-power, high-performance lithium ion battery pack supervisor suitable for a variety of lithium ion battery pack applications.
