The LT1995 is a high speed, high slew rate, gain selectable amplifier with excellent DC performance. Gains from -7 to 8 with a gain accuracy of 0.2% can be achieved using no external components. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a typical common mode rejection ratio of 79dB or more.

The amplifier is a single gain stage design similar to the LT1363 and features superb slewing and settling characteristics. Input offset of the internal operational amplifier is less than 2.5mV and the slew rate is 1000V/µs. The output can drive a 150Ω load to ±2.5V on ±5V supplies, making it useful in cable driver applications.

The resistors have excellent matching, 0.2% maximum at room temperature and 0.3% from -40°C to 85°C. The temperature coefficient of the resistors is typically -30ppm/°C. The resistors are extremely linear with voltage, resulting in a gain nonlinearity of 10ppm.

The LT1995 is fully specified at ±2.5V, ±5V and ±15V supplies and from -40°C to 85°C. The device is available in space saving 10-lead MSOP and 10-Lead (3mm × 3mm) DFN packages. For a micropower precision amplifier with precision resistors, see the LT1991 and LT1996.

Features and Benefits

Companion module for Active Learning labs on buck and boost power converters
Illustrates important concepts related to buck and boost converters:
- Continuous vs. Discontinuous Conduction Modes
- Open loop operation
- Voltage mode control
- Current mode control
Independently adjustable parameters: frequency, duty cycle, voltage/current mode
Onboard current sense amplifiers and adjustable load minimize equipment requirements.

Product Details

The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:

Boost and Buck converter elements and open-loop operation
Buck Converters: closed loop operation
Boost Converters: closed loop operation

The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:
