CIRCUIT060058
概覽
This single-supply precision absolute value circuit is optimized for low-input voltages. It is designed to function up to 50 kHz and has excellent linearity at signal levels as low as 5 mVpp. The design uses a negative charge pump (such as LM7705) on the negative op amp supply rails to maintain linearity with signal levels near 0 V.
特點
- Input: Vi = 5 mV to 400 mV
- Output: Vo = 2.5 mV to 200 mV
- Supply:
- Vcc = 5 V
- Vee = -0.23 V
- Vref = 0 V
