The CA3130EZ from Renesas is a BiMOS Operational Amplifier that is ideal for ground-referenced single supply amplifiers, fast sample-hold amplifiers, long-duration timers, and monostable, high input impedance comparators (ideal interface with digital CMOS), high-input-Impedance wideband amplifiers, voltage followers (e.g., follower for single-supply D/A converter), voltage regulators (permits control of output voltage down to 0V), peak detectors, single-supply full-wave precision rectifiers, and photo-diode sensor amplifier applications. It requires a supply voltage of up to 16 V and an input offset current of 0.5 pA. This amplifier provides an output voltage of 13.3 V and an output current of less than 45 mA. It delivers a large signal voltage gain of 320 kV/V and has a common mode rejection ratio (CMRR) of 90 dB.
This op-amp incorporates gate-protected P-channel MOSFET (PMOS) transistors at the input side and offers very high input impedance, low input current, and an impressive speed, which brings the common-mode input voltage down to 0.5 V below the negative supply terminal. It integrates a CMOS transistor pair at the output that maintains precise output voltage swings within 10 mV of either terminal of the power supply, even under high load impedance conditions. It offers versatility and ease of use with the ability to conveniently provide phase compensation using a single external capacitor, making it ideal for a wide range of supply voltage applications. This RoHS-compliant op-amp offers additional flexibility with terminals for offset voltage adjustment, accommodating applications that require offset-null capability while also offering terminal provisions for convenient strobing of the output stage. It is available in a surface-mount package that measures 5 x 6.20 x 1.75 mm.
