Description : High-speed Operational Amplifier evaluation board kit

The KITHSEVAL/STDL high-speed Operational Amplifier evaluation board kit is comprised of:

■ 5 unmounted evaluation boards,
■ a CDROM of documentation, including:
  – a user manual for the boards,
  – datasheets for the supported high-speed Operational Amplifiers.
 
Each evaluation board allows the user to evaluate one Operational Amplifier at a time. Each  evaluation board is generic for a given package and number of channels:

■ The SOT23_SINGLE_HF board supports a single-channel high-speed Operational Amplifier in the SOT23-5L package.
■ The SO8_SINGLE_HF board supports a single channel high-speed Operational Amplifier in SO8 package.
■ The SO8_DUAL_HF board supports a dual high-speed Operational Amplifier in the SO8 package.
■ The S08_S_MULTI board supports a high speed Operational Amplifier in the SO8 package for both inverting and non-inverting configurations, dual or single supplies.
■ The SO14_TRIPLE board supports a triple high-speed op-amp in the SO14 package with video application considerations.

Each of these evaluation boards is unmounted PCB, and must be mounted with the necessary external components. The choice of these external components depend upon which Operational Amplifier is being evaluated, as well as the desired evaluation conditions (desired gain, etc.). A layout example is shown for each demoboard in the user manual on the kit’s CDROM.

GENERAL DESCRIPTION
The ALD1721E is a monolithic rail-to-rail precision CMOS Operational Amplifier with Integrated user programmable EPAD (Electrically Programmable Analog Device) based offset voltage adjustment.

Description : Low Voltage Rail-To-Rail Sleep-Mode Operational Amplifier

Low Voltage Rail-To-Rail Sleep-Mode Operational Amplifier

The MC33304 is a monolithic bipolar Operational Amplifier. This low voltage rail–to–rail Amplifier has both a rail–to–rail input and output stage, with high output current capability. This Amplifier also employs Sleep–Mode technology. In sleepmode, the micropower Amplifier is active and waiting for an input signal. When a signal is applied, causing the Amplifier to source or sink ≥200 µA (typically) to the load, it will automatically switch to the awakemode (supplying up to 70 mA to the load). When the output current drops below 90 µA, the Amplifier automatically returns to the sleepmode.
Excellent performance can be achieved as an audio Amplifier. This is due to the Amplifier’s low noise and low distortion. A delay Circuit is incorporated to prevent crossover distortion.

• Ideal for Battery Applications
• Full Output Signal (No Distortion) for Battery Applications Down
   to ±0.9 VDC.
• Single Supply Operation (+1.8 to +12 V)
• Rail–To–Rail Performance on Both the Input and Output
• Output Voltages Swings Typically within 100 mV of Both Rails
   (RL = 1.0 mΩ)
• Two States: “Sleepmode” (Micropower, ID = 110 µA/Amp) and
   “Awakemode” (High Performance, ID = 1200 µA/Amp)
• Automatic Return to Sleepmode when Output Current Drops Below
   Threshold, Allowing a Fully Functional Micropower Amplifier
• Independent Sleepmode Function for Each Amplifier
• No Phase Reversal on the Output for Overdriven Input Signals
• High Output Current (70 mA typically)
• 600 Ω Drive Capability
• Standard Pinouts; No Additional Pins or Components Required
• Drop–In Replacement for Many Other Quad Operational Amplifiers
• Similar to MC33201, MC33202 and MC33204 Family
• The MC33304 Amplifier is Offered in the Plastic DIP or SOIC
   Package (P and D Suffixes)

Description : 110kHz, Operational Transconductance Amplifier Array

Description
The CA3060 monolithic Integrated Circuit consists of an array of three independent Operational Transconductance Amplifiers (see Note). This type of Amplifier has the generic characteristics of an Operational voltage Amplifier with the exception that the forward gain characteristic is best described by transconductance rather than voltage gain (open-loop voltage gain is the product of the transconductance and the load resistance, gMRL). When operated into a suitable load resistor and with provisions for feedback, these Amplifiers are well suited for a wide variety of Operational-Amplifier and related applications. In addition, the extremely high output impedance makes these types particularly well suited for service in active filters.

Features
• Low Power Consumption as Low as 100mW Per Amplifier
• Independent Biasing for Each Amplifier
• High Forward Transconductance
• Programmable Range of Input Characteristics
• Low Input Bias and Input Offset Current
• High Input and Output Impedance
• No Effect on Device Under Output Short-Circuit Conditions
• Zener Diode Bias Regulator

Applications
• For Low Power Conventional Operational Amplifier Applications
• Active Filters
• Comparators
• Gyrators
• Mixers
• Modulators
• Multiplexers
• Multipliers
• Strobing and Gating Functions
• Sample and Hold Functions
