FEATURES

DESCRIPTION

The LTC^®6362 is a low power, low noise differential op

amp with rail-to-rail input and output swing that has been

optimized to drive low power SAR ADCs. The LTC6362

draws only 1mA of supply current in active operation, and

features a shutdown mode in which the current consump-

tion is reduced to 70μA.

1mA Supply Current

Single 2.8V to 5.25V supply

Fully Differential Input and Output

200μV Max Offset Voltage

260nA Max Input Bias Current

Fast Settling: 550ns to 18-Bit, 8V Output

P-P

Low Distortion: –116dBc at 1kHz, 8V

Rail-to-Rail Inputs and Outputs

3.9nV/√Hz Input-Referred Noise

180MHz Gain-Bandwidth Product

34MHz –3dB Bandwidth

P-P

The amplifier may be configured to convert a single-

ended input signal to a differential output signal, and is

capable of being operated in an inverting or noninverting

configuration.

Low offset voltage, low input bias current, and a stable

high impedance configuration make this amplifier suit-

able for use not only as an ADC driver but also earlier in

the signal chain, to convert a precision sensor signal to

a balanced (differential) signal for processing in noisy

industrial environments.

Low Power Shutdown: 70µA

8-Lead MSOP and 3mm × 3mm 8-Lead DFN Packages

APPLICATIONS

16-Bit and 18-Bit SAR ADC Drivers

Single-Ended-to-Differential Conversion

Low Power Pipeline ADC Driver

The LTC6362 is available in an 8-lead MSOP package and

also in a compact 3mm × 3mm 8-pin leadless DFN pack-

age, and operates with guaranteed specifications over a

–40°C to 125°C temperature range.
