LT1004CD-2.5 – TEXAS INSTRUMENTS

The LT1004CD-2.5 is a precision, low-power, single operational amplifier from Analog Devices, specified for a 2.5V ±1% supply voltage. This specific part number denotes a CD package (SOIC-8) and distinguishes it from variants with different supply voltage tolerances. Its key features include a low input bias current (typically 25pA), high input impedance (10¹²Ω), and low input offset voltage (typically 1mV). The LT1004CD-2.5 operates over a 0V to 2.5V single-supply range, making it ideal for battery-powered applications or systems with limited voltage headroom. Its low noise performance (10nV/√Hz at 1kHz) is beneficial in sensitive instrumentation and signal conditioning circuits. Common applications include precision instrumentation amplifiers, low-noise voltage followers, and current-to-voltage converters in systems requiring accurate measurements within the specified voltage range. Unlike higher-voltage counterparts, its low supply voltage necessitates careful consideration of common-mode voltage limitations and potential for rail-to-rail limitations at the output, but the low power consumption is a significant advantage in portable or space-constrained designs. The tight supply voltage tolerance (+/-1%) ensures consistent performance across different units.
