LM7321/LM7321Q Single/ LM7322/LM7322Q Dual Rail-to-Rail Input/Output ±15V, High

Output Current and Unlimited Capacitive Load Operational Amplifier

Check for Samples: LM7321, LM7322

FEATURES

DESCRIPTION

The LM7321/LM7321Q/LM7322/LM7322Q are rail-to-

rail input and output amplifiers with wide operating

currents.

The

•

Wide Supply Voltage Range 2.5V to 32V

Output Current +65 mA/−100 mA

Gain Bandwidth Product 20 MHz

Slew Rate 18 V/µs

LM7321/LM7321Q/LM7322/LM7322Q are efficient,

achieving 18 V/µs slew rate and 20 MHz unity gain

bandwidth while requiring only 1 mA of supply current

per

amp.

The

LM7321/LM7321Q/LM7322/LM7322Q performance is

fully specified for operation at 2.7V, ±5V and ±15V.

•

Input Voltage Noise 15 nV/√Hz

Input Current Noise 1.3 pA/√Hz

Supply Current/Channel 1.1 mA

Distortion THD+Noise −86 dB

Temperature Range −40°C to 125°C

LM7322/LM732Q parts are tested at −40°C, 125°C,

and 25°C, with modern automatic test equipment.

High performance from −40°C to 125°C, detailed

specifications, and extensive testing makes them

suitable

for

industrial,

automotive,

and

communications applications.

Tested at −40°C, 25°C and 125°C at 2.7V, ±5V,

Greater than rail-to-rail input common mode voltage

range with 50 dB of common mode rejection across

this wide voltage range, allows both high side and low

side sensing. Most device parameters are insensitive

to power supply voltage, and this makes the parts

easier to use where supply voltage may vary, such as

automotive electrical systems and battery powered

equipment. These amplifiers have true rail-to-rail

output and can supply a respectable amount of

current (15 mA) with minimal head- room from either

rail (300 mV) at low distortion (0.05% THD+Noise).

There are several package options for each part.

Standard SOIC versions of both parts make

upgrading existing designs easy. LM7322LM7322Q

are offered in a space saving 8-Pin VSSOP package.

The LM7321/LM7321Q are offered in small SOT-23

package, which makes it easy to place this part close

to sensors for better circuit performance.
