EL2245C, EL2445C

Dual/Quad Low-Power 100MHz Gain-of-2 Stable Op Amp

Features

General Description

• 100MHz gain-bandwidth at gain-

of-2

• Gain-of-2 stable

• Low supply current (per amplifier)

= 5.2mA at V_S= ±15V

• Wide supply range

The EL2245C/EL2445C are dual and quad versions of the popular

EL2045C. They are high speed, low power, low cost monolithic oper-

ational amplifiers built on Elantec's proprietary complementary

bipolar process. The EL2245C/EL2445C are gain-of-2 stable and fea-

ture a 275V/µs slew rate and 100MHz bandwidth at gain-of-2 while

requiring only 5.2mA of supply current per amplifier.

= ±2V to ±18V dual-supply

= 2.5V to 36V single-supply

• High slew rate = 275V/µs

• Fast settling = 80ns to 0.1% for a

10V step

The power supply operating range of the EL2245C/EL2445C is from

±18V down to as little as ±2V. For single-supply operation, the

EL2245C/EL2445C operate from 36V down to as little as 2.5V. The

excellent power supply operating range of the EL2245C/EL2445C

makes them an obvious choice for applications on a single +5V or

+3V supply.

• Low differential gain = 0.02% at

A_V= +2, R_L= 150W

The EL2245C/EL2445C also feature an extremely wide output volt-

age swing of ±13.6V with V_S= ±15V and R_L= 1000W. At ±5V,

output voltage swing is a wide ±3.8V with R_L= 500W and ±3.2V with

R_L= 150W. Furthermore, for single-supply operation at +5V, output

voltage swing is an excellent 0.3V to 3.8V with R_L= 500W.

• Low differential phase = 0.07° at

A_V= +2, R_L= 150W

• Stable with unlimited capacitive

load

• Wide output voltage swing

=±13.6V with V_S= ±15V,

R_L= 1000W

At a gain of +2, the EL2245C/EL2445C have a -3dB bandwidth of

100MHz with a phase margin of 50°. They can drive unlimited load

capacitance, and because of their conventional voltage-feedback

topology, the EL2245C/EL2445C allow the use of reactive or non-lin-

ear elements in their feedback network. This versatility combined with

low cost and 75mA of output-current drive make the

EL2245C/EL2445C an ideal choice for price-sensitive applications

requiring low power and high speed.
