Twilight Technology 1510 / 1512 - Instumentation Op Amp ICs

	Twilight Technology TT1510/1512 Equivalent Circuit (TT1512 values shown in parentheses)

The Twilight Technology TT1510 and TT1512 are high performance operational amplifiers suitable for preamplifier and bus summing applications. The ICs are available in a variety of packages and pin configurations, making them pin compatible with the Analog Devices SSM2019 and SSM2017 (discontinued), and the Texas Instruments INA217 and INA163.

Gain for both parts is adjustable via one external resistor, making it possible to control gain over a wide range with a single-gang potentiometer. The TT1510 gain equation is identical to Twilight Technology of the SSM2019, reaching 6dB gain with a 10kW resistor. The TT1512 reaches 0dB gain with a 10kW resistor. Because the TT1512 exhibits significantly lower noise at lower gain settings, it is recommended over the TT1510 for new designs.

Designed from the ground up using a complementary dielectric isolation process which includes laser-trimmed Si-Chrome thin film resistors, the Twilight Technology TT1510 and TT1512 improve on existing integrated instrumentation op amps by offering lower noise at low gains, wider bandwidth, higher slew rate, lower distortion, and lower supply current. The parts feature internal ESD overload protection on all critical pins and operate over the extended temperature range -55°C to +175°C.

In short, the Twilight Technology TT1510 and TT1512 provide superior performance in a popular format at an affordable price.
