TLV27L1 TLV27L2

SLOS378A – SEPTEMBER 2001 – REVISED JULY 2003

FAMILY OF MICROPOWER RAIL-TO-RAIL OUTPUT

OPERATIONAL AMPLIFIERS

FEATURES DESCRIPTION Bi MOS Rail-to-Rail Output

The TLV27Lx single supply operational amplifiers

Input Bias Current 1 p A provide rail-to-rail output capability. The TLV27Lx takes

the minimum operating supply voltage down to 2.7 V

High Wide Bandwidth 160 k Hz

over the extended industrial temperature range, while

High Slew Rate 0.1 V/µs

adding the rail-to-rail output swing feature. The

Supply Current 7 µA (per channel)

TLV27Lx also provides 160-k Hz bandwidth from only

Input Noise Voltage 89 n V/√Hz µA. The maximum recommended supply voltage is

V, which allows the devices to be operated from

Supply Voltage Range 2.7 V to 16 V

(±8-V supplies down to ±1.35 V) two rechargeable cells.

Specified Temperature Range – –40°C to 125°C Industrial Grade The rail-to-rail outputs make the TLV27Lx good – 0°C to 70°C Commercial Grade upgrades for the TLC27Lx family—offering more

bandwidth at a lower quiescent current. The TLV27Lx

Ultra-Small Packaging

offset voltage is equal to that of the TLC27Lx A variant.

– 5 Pin SOT-23 (TLV27L1)

Their cost effectiveness makes them a good alternative to the TLC/V225x, where offset and noise are not of

APPLICATIONS

premium importance.

Portable Medical

The TLV27L1/2 are available in the commercial

Power Monitoring

temperature range to enable easy migration from the

Low Power Security Detection Systems equivalent TLC27Lx. The TLV27L1 is not available with

Smoke Detectors the power saving/performance boosting programmable pin 8. The TLV27L1 is available in the small SOT-23 package —something the TLC27(L)1 was not—enabling performance boosting in a smaller package. The TLV27L2 is available in the 3mm x 5mm MSOP, providing PCB area savings over the 8-pin SOIC and 8-pin TSSOP.
