The 7D13 consists of an analog pulse width modulator front-end built with 741 op amps and dual FETs, and a 3½ digit counter section using standard 74xx TTL parts which is interfacing with the [[7000 series readout system|readout system]]. The front end is isolated by transformers used for pulses and a floating ±15 V supply. | The 7D13 consists of an analog pulse width modulator front-end built with 741 op amps and dual FETs, and a 3½ digit counter section using standard 74xx TTL parts which is interfacing with the [[7000 series readout system|readout system]] (through a [[155-0038-00]] D/A converter).
