GENERAL DESCRIPTION
The OP215 offers the proven JFET-input performance advantages of high speed and low input bias current with the tracking and convenience advantages of a dual op amp configuration.
Low input offset voltages, low input currents, and low drift are featured in these high-speed amplifiers.
On-chip zener-zap trimming is used to achieve low VOS, while a bias-current compensation scheme gives a low input bias current at elevated temperature. Thus, the OP215 features an input bias current of 1.4 nA at 70∞C ambient (not junction) temperature which greatly extends the application usefulness of this device.
Applications include high-speed amplifiers for current output DACs, active filters, sample-and-hold buffers, and photocell amplifiers. For additional precision JFET op amps, see the OP249 and AD712 data sheets.

TI
Texas Instruments

Description
The INA21x are voltage-output, current-shunt monitors (also called current-sense amplifiers) that are commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This series of devices can sense drops across shunts at common-mode voltages from –0.3 V to 26 V, independent of the supply voltage. Six fixed gains are available: 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V, or 1000 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.
These devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 µA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C), and offered in SC70 and UQFN packages.

ON-Semiconductor
ON Semiconductor

The NCP1215A is a controller for low power off−line flyback Switchemode Power Supplies (SMPS) featuring low size, weight and cost constraints together with a good low standby power performance. The operating principle uses switching frequency reduction at light load by increasing the OFF Time. Also, when OFF Time expands, the peak current is gradually reduced down to approximately 1/4 of the maximum peak current to prevent from exciting the transformer mechanical resonances. The risk of acoustic noise is thus greatly diminished while keeping good standby power performance.
A low power internal supply block also ensures very low current consumption at startup without hampering the standby power performance.
A special primary current sensing technique minimizes the impact of SMPS switching on control IC operation. The choice of peak voltage across the current sense resistor allows dissipation to be further reduced. The negative current sensing technique offers advantages over a traditional approach by avoiding the voltage drop incurred by traditional MOSFET source sensing. Thus, the IC drive capability is greatly improved.
Finally, the bulk input ripple ensures a natural frequency dithering which smooths the EMI signature.

Features
• Pb−Free Package is Available
• Variable OFF Time Control Method
• Very Low Current Consumption at Startup
• Natural Frequency Dithering for Improved EMI Signature
• Current Mode Control Operation
• Peak Current Compression Reduces Transformer Noise
• Programmable Current Sense Resistor Peak Voltage
• Undervoltage Lockout
• Pb−Free Packages are Available

Typical Applications
• Auxiliary Power Supply
• Standby Power Supply
• AC−DC Adapter
• Off−line Battery Charger
